So, the issue isn't caps. The issue is players. We got that pinned down, right?
If you wanna improve Roleplay, remove the roleplay-before-engaging rules. The server population will rise, cloaks would become amazing tools, and those who'll bother with roleplaying will step up their game. Iunno why Caps would be an issue in such a setting. Keep rules for interaction between pirates, miners and traders, though.
