I would open a throw away account to post a question like this, too. There are Milspec M1/M14 rubber butt pads. https://www.amazon.com/Ultimate-Arms-Gear-Insignias-Springfield/dp/B008UAQ06A
Other than that, I would recommend a AR-15 with a H3 buffer, gamer internals, and pink anodizing for you.
These have been posted here before. I have no idea which is better or how well they would work, though.
