Okay, I got the V&H VO2 air cleaner kit in, and measured it. The filter front/exterior surface is 5.5" in diameter, the Screamin' Eagle medallion is about 5" in diameter. So it would almost fit, the black edge would I guess just overlap with the black face of the exterior surface of the V02 filter.
The bigger problem is, I found the installation instructions
for the Screamin' Eagle medallion (well, the whole Stage 1 air cleaner kit, actually). And it appears that the medallion is actually just a peel & stick sticker(!) I thought it was a metal plate, but it's a sticker. So, for that matter, is the "750 Liquid Cooled" medallion that's currently on the stock airbox. You're supposed to "carefully remove and discard" the original medallion, then peel & stick the new one in its place. Well, heck, if I could carefully remove the original, I should be able to just stick that right on the VO2, right? Er, not so much. And so, I don't think the Screamin' Eagle medallion idea will work either.
The genius in Unaclocker's approach is that by slicing off the front of the airbox, you're retaining the physical plate that the medallion attaches to, which makes for a physical cover. If you were to try to do what I was thinking of, just sticking the medallion over the face of the VO2, then you'd be covering up the three mounting screws that bolt the filter to the bike, probably not a great idea. That's no problem in Unaclocker's approach, as removing the center bolt will remove the cover and then you have access to the filter mounting bolts. But with the peel 'n' stick, that means to get at those bolts, you're probably going to have to destroy the medallion. Meh.
So, it's back to square 1, finding someone with actual mechanical skill to properly snick off that cover faceplate from the original stock air cleaner box, and bolting that to the V&H air filter. On the other hand, for those who would want the Screamin' Eagle logo on their bike, you could always apply it exactly the same way as you would have otherwise, since that same mounting faceplate will be there.
