Having things fade out is probably a better idea, thanks. I'll do that in the future.
And yes the REV100 does have a nice crappy graininess to it. I only used it here for a very quiet delay thing in the background, where I hit the pick against my desk along with the snare. I originally wanted to use it with some vocal/choral thing but ditched it (didn't want to oversaturate the track). But yeah really pushing it and using it just for a grainy pad sounds like a great idea, I'll give it a shot in the future.
