i dont think so, because when brolli fights ssj2 gohan, gohan hasnt trained in years and he's much less powerful.... thats just my opinion though, i thought there was only 1 level of Legendary super saiyan, it's just like USSJ but he doesnt loose the speed........... If you recall Goku at ssj3 is no where near as powerful as Gogeta ssj 1, so think how strong ssj4 gogeta is...
