An update to this, some further research on other forums does indeed agree that the G&P stocks will work, but the most solid thing I can find about the outer barrel is that a G&P one will work "With some Modification".

I'm not big on that, when you're talking a somewhat pricey part, so I think I'll just try to get my hands on an A&K/CA Para outer barrel... which is where my google-fu skills fail me, I can't seem to find a place that sells either...
