Though the DPMS hammers will work on the Colt/RRA type 9mm uppers, I'd recommend swapping a 9mm hammer in with the 9mm buffer when using the 9mm upper.

Also, don't forget to get your lower engraved before you get your approved form 4 back. Remember to register it on the F4 as both 9mm and 223 or you'll need to send a letter of intent to the NFA branch to update your NFA status.
