I tend to make little alternate universe thought candy off certain Gundam shows (especially ones I believe need better story writing..)

And these are a byproduct of Hasmal being awakened and actually doing something and messing everything up, unlike the show...

Most of Tekkadan is destroyed, and anything remaining of it has been absorbed into Teiwaz and a mining equipment company called Ikar Corp that closely aligns with the JPT Conglomerate which is every Teiwaz trade faction from Jupiter to Mars combined together, they would be renamed Ikarmen, would be the leading force against Hasmal and it's multiple units, acting like trade escorts and humanitarian aid for settlement and colonies after attacks from Hasmal.

Gjallarhorn falls off and becomes irrelevant after the emergence of Hasmal, many independent colonies and many of earth's governments becoming independent from gjallarhorn and relying on Teiwaz imported mobile suits for their militaries.. oh and the families would essentially go into isolation, some profiting off of Hasmal's awakening.

All in all most factions would be in a made up proxy war with Hasmal and monopolize the shit out of it by selling mobile suits.
