CaraPils doesn't really taste like anything, it just adds body and head retention, which is fine. I definitely wouldn't add Munich malt. Doing a mini-mash with some 6-row or 2-row and flaked maize, and maybe even just a handful of flaked oats (you wouldn't want to overdo it), would probably be your best choice.
