Okay we have a small problem ...
No way I can roll on 20s!!!
So I'm gonna put the 375s on, put the 20s on the HyHoe, then order a new set of 375s, then put those on the Denali, then put back the old 375s on the HyHoe, then sell the 20s.
I don't see another viable option which makes life worth living.
Why not switch wheels and order those blank caps like you talked about?
