I would really like to see a LEAF with RPF1's! It's an amazingly light wheel for the price. It would look great in +2 and might still give a total weight savings in that size. Low RR tires are pretty common in different sizes so it could work well.
I doubt you will see an advantage going with plus sizing for a couple reasons. First off, the majority of the mass and inertia of a wheel is in the rim. Moving it outward does negate any total mass losses. Also, tires as efficient as the ones on the LEAF are not available in the larger size. Plus going with a shorter sidewall will only hurt ride, but it will help on turn-in, if that is your goal as well. I have a set of Forged 18" Rays wheels for another car that weigh 16 lbs each. I mounted them on the LEAF as they did fit but they looked so stupid that I immediately too them back off.
