New account again, making nice progress, arena team is currently this (All level 47):
AA (L) 4* G6 (4 off 7)
GS 4* G6 (1 off 7)
Luke 3* G6 (2 off 7)
QGJ 3* (3 off 7)
Phasma 4* (2 off 7)
I think AA is useful at the start, but in the long game he isn't a top lead.
Could ST Han be viable as lead if I focused on him early? (I am working on him now)
ST Han (L)
GS
QGJ
Phasma
AA/Luke/Leia (could get her to 4* quickly then leave her while I level ST Han up)/Rey (long term)
I've heard people say Han lead pairs well with RG. The idea is that when characters are knocked into yellow, RG auto-taunts, then the yellow character (probably your DPS) gains offense and survives to use it. And since they had defense up while green, they probably didn't go straight from green to dead.

Feel Han or even Phasma may be a better idea for lead
I've actually tried both ST Han and AA leads and dropped rank much more with han
