I can't remember, was it ever stated that Gin had a hollowfication side or not? I don't remember seeing that in the Aizen arc.
Aizen directly after Isshin....hmmm possible though I doubt it...He was playing the game far behind the scenes. To go directly after a captain before he was certain is something I can't stomach seeing Aizen doing .I am sure if Isshin did in fact beat the first Arrancar (mock), Aizen for sure sent a stronger one. After analyzing the results he probably then made Grand Fisher??? (guessing like a mofo)... Gin did not have a hollowfied state. He would not stoop that low..as his goal was Aizen himself.
