I've seen that done before, seems like some members here have done that also. I don't think it would cause any malfunction issues. Personally, I'd stay minimalist and not remove any more than necessary to achieve a good purchase. It's a good solution to the issues you describe.
I believe that is Ole Jocko's gun used in that video. I could be wrong, but I recall someone did a video using his gun and I know it had a ton of rounds thru it.
