Hmmm...! As a Bépo user, one wonders why you ask at the Colemak forum? Maybe because we use PKL so much? :-) Bépo exists for PKL too, so that may be your angle. In fact, my dead key tables owe much to the Bépo ones.
Using AutoHotkey scripts together with PKL may be tricky, if they use low-level hooks. But if not, they may run at the same time without trouble. Have you tried that? Other than that, no: PKL doesn't support other scripts except by including them and recompiling the code (making sure that no conflicts are created). Which is complex.
What I'd do, personally, would be to use Extend mappings! With Extend, Caps+ZXCV produce your desired results. I use them a lot. In addition, you have nice navigation possibilities. I think Extend is a great tool for RSI alleviation. Check out my Extend topic, linked to from my Big Bag topic. In my PKL files there's no Bépo but a lot of nice Extend mappings. You could add your layout to my files.
I'm not sure whether PKL actually supports it, but the KLC files that PKL is based off do support Ctrl+key mappings. If this is indeed possible, then it's a simple matter to just edit the mappings you want into your Bépo layout pkl.ini file!
While we're at it, also consider some ergonomic mods like Angle and Wide for your RSI. And of course I'd recommend Colemak-Curl(DH) but if you were interested in that I guess you'd have said so already. ;-)
