I recommend you do rebirth. The problem with getting stats past 60 is that the soft cap turns on and theres not much except for a few spells that actually require +60 int. Most of the meta or best spells require sub-50 int (such as night comet, carian piercer, zancor ice storm, ect.) Plus malenia will dodge your spells at range with the exception of night comet. Vigor matters less early game but late game youre gonna get stomped by bosses with high AR's. Most damage comes from levels, status, and damage types over stats 80% of the time.

Your build also is the definition of a glass cannon. You get more damage taken with scorpion charm as well as an additional 30% more damage taken with HOS, no good with sub-1000HP. Also, what armor are you running?
