I'd love to see H5 on PC. That game's multiplayer was great, as was the customization. I used to play the game on XBOX One before I moved over primarily to PC, and I wish I could go back and relive the times I had on that game's multiplayer. That, and I never got to play Infection mode on H5, and didn't get to play it at all until Reach launched on PC.
All that I ask out of a H5 PC port, however, is to have cross progression with the XBOX version. I had the steelbook edition as a birthday gift and as such, I had the Warzone REQ pack on top of the Mjolnir Mk VI (normal and scratched) as well as a ton of great banners. I've still got that steelbook lying around my room somewhere, disk and all still inside, and dossiers still sealed.
