Note 7 Port ROM?

[RileyIssKing]

I have been seeing videos on the new "Grace UX" and I love it. I know the s7 is supposed to get it with nougat but there is a rom for the s7. I know of Jesse's note 7 port, and the on the edge rom, but how can I flash it? This phone can't have a custom recovery but maybe flashfire will work? I know that the roms have a custom kernel so you'll be stuck in dm-verity recovery but any workarounds? Really want that rom. Anything helps! Thanks!
