Would it be worth my time to instead of swapping a WRX engine into my car, put forged internals in my existing RS and an STi head and turbo it? Is an STi head even compatable with an RS block? the idea just popped into my head so I thought I'd ask.

That is what Skully has done on here. You should search for his thread.
That's what I'm currently doing -the sti heads.
And yes, it's cheaper by quite a bit.

Put in STi internals (crankshaft,pistons,rods,race bearings) and call it a day. I'm currently doing it to my motor (same as yours). The cost is so much cheaper than buying a new STi shortblock!

Sti crank is identical to the stock RS one, plus the crank isn't the weak link to begin with. Also remember the open deck block is a limiting factor in a very high horsepower build.
