P50E in open-back R112 Cabinet?

Hi, long time VHT/Fryette user and supporter, I supported the GP/DI project as well as the R112 cab, also run a custom ordered Fryette 2562 (2502 with 6L6).

I’m currently trying to put a P50E in the R112 for some tones (inspired by Fatbottom 412 P50E), while I know it’s open and different, I’m hoping it would work ok, any thoughts?

Also, the webstore doesn’t let me order a P50E direct, I’ve emailed support and sales - can someone help me put together an order?

Thanks!
