Yeah, I've used camo tape to tidy up my helmet straps and the harness on the back of my lower face mesh mask - although I've had to add a few stitches to keep it in place because the glue hasn't stood the test of time. It would be ok for a perfect prism foregrip, like the same cross sectional shape/size all the way down, probably even with the mouse tail underneath, but any ergonomic shaping would bollock it right up.
