As it was made quite clear by Genesis in another suggestion thread, Basilica cannot be changed (I know, we're not talking about Basilica). Point is, if he can't change that skill, then I don't think he can modify many others, as they are apparently interlinked with each other. It's unfortunate, since many of the modifications seemed fair and worthwhile.
Unless Genesis figures out a way to change skills or something similar, this thread will be in limbo in the suggestion thread.
