I have a hard time seeing either one as Hal, to be honest.
I could buy RR as Kyle (and a "hell yes" re: Wally West), but Hal just seems wrong.
Pre-Parallax Hal isn't just wise-cracking and funny, he truly believes that he's the best there is, and he needs everyone to know it. Anything less means he's not doing his best.
Kyle, on the other hand, began with massive self-confidence issues because, well, he wasn't Hal, and he was completely alone (no corps, no acceptance, fridged girlfriend, etc). He was funny too, but his humor was self-deprecating a lot, and he did it to cover up his insecurities. For better or for worse, RR's roles seem to use variations of this theme, and that's why Kyle makes more sense (to me) for him.
As for Fillion, I've really only seen him in Firefly and Dr. Horrible, so my image of him is a sarcastic veneer covering a really dark, depressing view of life, which really isn't a good match for pre-Parallax Hal (post-Parallax, on the hand, maybe).
The superhero I think Fillion would rock as would be Booster Gold. Never happen, but I can wish.
