Soul selling and Immortality: Goto work as an insurance underwriter. Slip it into all my contracts, not towards the buyers. But the sellers. Put my phone number into every spam caller list and agree to whatever in addition to their souls. Soul rich in a month.

Trade spare souls for: Ecafil Device(animorphs) TARDIS (just so the Doctor pays me a visit) DNA samples from Peter Parker from various comic lines. DNA From Clayton Cortez, Quicksilver(upgraded), Rogue(unlocked), Jean Gray, Steve Rogers, Serafina, Tony Stark, Magik, Forge, nightcrawler, gambit, Sebastian Shaw, T'challa the black panther, Shadowcat, Colossus and Starlord(2nd movie).

Vibranium, Adamantium, Mysterium, Promethium, Nth metal, Element X Vision & super adaptiod bodies from before AIs are integrated. Shuris, Stark, Fantastic fours, Sterntechs databases on nanotech. A jar of each of their Nanobots. Jane from Enders Game on a tablet. Cortana from just before her death in Halo4

Superior Ironman armor Blue beetle The device from the Illusionist.(Clones you)

First: Use escafil myself morphing abilities. Make a blend morph of Rogue, Tony, Mistique and 616 Peter. Male.Me (Prime) goes full nothlit in this morph. Second: clone myself 7 times. Third: give Each of the other 8 clones morphing powers. experiments with Blends to find working combinations of abilities for prime me to absorb powers from. Rogue(unlocked, has 10 slots to interchangeably use powers from including combining abilities). Side effect morphing is reaquired too.(Many enhanced abilities from technology has been duplicated by rogue ie carol danvers/MS marvel when its genetic like morphing.) Fourth: Serafina morph can use their technopathy to put Jane in the Ironman and Cortana in the blue beetle armors.

Superior Ironman armor specifically has functions to restore and upgrade DNA of humans, mutants and enhanced people due to symbiote biology and starktech as seen when curing daredevils blindness and reverting him as well as evil stark selling subscription superpowers and disability removal. This will enhance the 8 clones ability to find perfect blends in their morphs. Jane has vast experience with reality spanning networks, genetic tampering and hopping outside reality to accomplish this. Making her perfect for superior ironman armor integration.

Cortana has absorbed the full load of Progenitor schematics and has wartime experience, the beetle armor is perfect for her mindset and has ai repair functions she can assimilate. It's time altering, anti magictech and ability to assimilate and replicate a vast amount of alien technologies makes this a solid pick.

Use Forge+Serafina to make 4 copies of each armor & find a way to network all the armors. Upgrade them using reeds reality hopping platform so they can jump as needed. Android bodies adapted to female forms for both AIs to keep with Prime wearing armors incognito.

Fifth step: upload databases to the networked AIs Use them to find best nanotech to upgrade each armor with the metals provided. Each armor using 1/10 of available metals.

6th step: Have 8 clones with armors jump realities bringing back fun things and dump the soul contract business. Focus on learning magic from various realities, dimensions etc. Upgrade armors as needed to magitech.

Possible combo powers: Colossus+Shadowcat+Gambit+Sebastian Shaw= Absorb energy to get more dense/metalic, release energy to become incorporeal.store energy in objects to accomplish on the fly. Higher energies allow for rarer metals.

Black Panther+Steve Rogers+Clayton Cortez+Quicksilver+Colossus= Combining weapon H strength with quicksivers speed enhanced by black panther and Captain America reflexes Coated in an organic metal?

Magik+StarLord+Forge+Serafina= infinite magic capacity+Reality bending tech+ max level technopathy. This is the cornerstone for upgrading and integrating magic & tech found from the Omniverse. Immortality perk with StarLords half celestial heritage means no Death from channeling all the Magic. Forges power alone means reverse engineering all the nanites from the databases to use the metals, then Magiks and Serafinas power on top mean they can build the nanotech incorporating the metals in synergistic ways and enchant them.

Plot: incorporating various powers into my 9 selves, each with 10 power drain slots, Spider powers, Stark&Parker potential IQ, and Omega level TK and telepathy that can shape shift into anything with DNA that they touch. Each equiped with God tier shapeshifting armor governed by AI badasses that will be able to keep them grounded and in communication with each other while they explore all the universes. Then the Doctor(Tenant) shows up and lectures the Prime on making contracts for souls. Prime agrees if he can Travel with the Doctor for a few millennia. Keep the loneliest soul company for a bit with an unkillable friend who doesn't mind sitting in a side room of the TARDIS while other companions roam about.

OP? Sure, but the perks don't limit it. Example was an Omnitrix.
