The thing is the sounds are all ripped from the show and not every character and every form of that character uses the moves they have in ESF. To the best of my knowledge Vegeta only uses gallick/gallit gun twice ever in DBZ, the sound he's got atm isn't even from that move, its his big bang attack in movie 6 ("Enough, you will not make a fool out of me!" used on metal coola and goku), same applies with Final Flash only being used once (I think) I'd suggest stealing them from existing, official FUNimation games [turn the music off in Budokai 2 and u can get some good ones] but I agree with you, the same sounds+voices over and over gets tiring after a while, you could replace the existing .wav's with others from different soundpacks, but the way it works now is one sound per move so you'd have to manually replace the sound each time you wanted to hear it differently.
