However on the basis of SSJ3 Goku (GT)>Super Vegito what people are forgetting is the fact that GT was based off of the anime. So by that logic we have Base Vegito>>Gohan Buu. So really unless SSJ2 Goku (GT) is at least in the league of Gohan Buu his SSJ3 form won't make him as good as Super Vegito, however it's probably not.
Goku's SSJ form in GT is roughly equal to Gotenks' SSJ form. Since I believe the SSJ2 multiplier to be at least 5-fold (from SSJ), and SSJ3 multiplier at 3-fold (From SSJ2) I figure SSJ2 Goku (GT) to be between Mystic Gohan & Gotenks Buu, closer to Gotenks Buu. SSJ3 Goku (GT) would be enough to surpass Base Vegito, but Super Vegito is still alot stronger. Bebi-Vegeta utterly destroyed SSJ3 Goku so he's probably close to Vegito's SSJ power. I do believe Goku would win, but still making SSJ3 Goku (GT) stronger than Super Vegito is overdoing it alot.
