Check with your state statutes... The DMV told me that if the engine number I provided didn't match the one in their database (generated based on the the VIN number), I couldn't register my bike in MN. I'm sure there is a way I COULD do it, but you know DMV employees are about as helpful as a swimsuit in a blizzard.
G, it depends on the state. I've seen some places where you ended up having to have a title for the frame and the motor if they have different VIN #'s but I think you end up just doing annual registration on one of the 2 VIN's. I know my dad has a Harley that is like that (here in Texas).

Don't do it. It will look like any other bike .... IMO.
Also too much trouble to swap everything twice with 2nd frame in the equation. Plastidip it if you must have black frame, and see if you really like it first
I've done this a couple of times in Ohio. Buying wrecked bikes without titles . Pick up a frame with a CLEAN CLEAR title is the key. Also buying in state helps. That way there is no out of state or salvage inspection. Just register it. I had my fun with them. Sold them and never heard anything about it. I think you will be ok seeing as how you own all of the parts. With the VIN numbers to prove so. Although it does vary by state as mentioned.
