if done right I don't see why it wouldn't look good. I think if you add 2 pieces of styrene, one to build the other clearance, it should make it so the bottom half wont have to flex and run the possibility of cracking your paint over time. Plastic well should hold fine, when it comes to styrene even plain old super glue holds extremely well. just not the gel kind.
This is knda what I'm talking about.

Just put the opposite part of the velcro in the gauntlet top and you should be set.
