Swapping Ranks on Paramount 450?

Short of doing a custom organ definition, is there any way to 'swap' one rank for another on the Paramount 450? Specifically, I'd prefer the non-roll Snare and the non-Reit Tamborine on the Accomp. manual. They both appear to be loaded -- just no way to use them (on that keyboard).

I'm afraid not, it would have to be a CODM thing, I think. There's actually loads of changes I would do to the 450, but it's just too much work! I think some of the ranks are gorgeous though.
