Hmm.. I think it may not work together then...
Seems to me that VS is getting the Battle Exp, like RPG Maker does by default. But with my plugin, every actor can get a different amount of Exp because of the level difference between them and trhe enemy. So it's not a fixed value, like Visustella and RPG Maker uses.
I do have a Battle Result plugin, but don't know the differences between mine and Visustella. But also, I didn't make it compatible either with the Exp By level. Will do someday. So I guess it is a dead end =/
