I don't think you want to do that second recipe as is, you're looking at 30% cara/crystal malts there. Munich is a base malt and not really like caramunich, which is more of a medium crystal malt. So in that recipe I would make up the munich and wheat with base malt, then sub in your caramunich for the medium crystal. I guess you could bump the caraaroma a little but you might want to be cautious, I understand it can be pretty potent.
