rota p-1, they dont make a 67.1mm bore with a 40+ offset, the 48mm offset had a 76 mm center bore, will that still work?
Are you sure about that? When I looked at this website
http://www.machiii.net/wheels/P1.html and their availability it's showing:

Maybe they listed it wrong, but I'd ask them. As for the hub bore question, you can always have a bigger hub bore. Some people will say you NEED hubcentric rings to let the wheel match up better with the hub, but I've heard it's just so you can mount the wheels easier. Personally, I don't think they're needed. I'm running my OZ Ultraleggeras with a hub bore of 74 I believe without any hub rings. Make sure the wheel is centered and torque the lugnuts equally. Should be good to go. Good luck.
