It'd be pretty cool, so long as it's not a copy over. Inmate is a great looking frame.Where the frame looks "fused" would be a cool place for some screws and gaskets. Some altercations to the earstems and nosepiece and yeah, you got yourself a kick-ass looking frame.
I'm actually surprised they didn't go the other direction with the Juliet and offer an O Matter style of it. Kinda like the Mars/Moon thing. I'm not saying I'm for it, but I think it probably would've sold considering the popularity of Juliet.
I love the orbital socket on the juliet and penny, thats the kind of design feature I'd love to see on a full frame x-metal, the reversed orbital socket on the pitboss looks amazing as well, the flex coupler nosebridge on every x-metal except the Half-X screams X-metal design to me so it would be really awesome if they carried that over, that said, as much of a romeo/juliet/penny fan as I am, I hope it's different enough to stand out from the rest of the line.
