Seems like the time is nigh.
Merlin 1 and 2 models ran on 87 octane with low compression pistons and developed 880 hp. so like GA engines there should be a route to modify the later Merlin variants to run on 94 UL. Again not cheap and there will be a performance penalty which will be partly mitigated by not having to carry a combat load, but definitely doable.
