No can do, those rocks don't just work like that. I'd have to radically shift that side of the map around to address those two.
I've heard this complaint before, but I honestly see it as an open ended deal. Bounty hunters and EJs have a way into the base and aren't shunned completely by the gate, while you as clones have the duty and job of maintaining active checks to ensure they aren't doing this. It all comes down to the funny base pass system y'all work with, as well.
