If what you say about the FAF is true, then that's certainly something the RAF should consider.
Some years ago when there was an experiment to send 3 ME students through the Prestwick scheme, my assessment (compared to the ex-Jetstream cours students) was that in a few areas the two groups were comparable - but in most areas the ex-Prestwick students were vastly superior!
Someone reaching a ME OCU straight through the RAF training machine won't have anything like enough PIC time even for a CPL these days - solo consolidation seems to be a thing of the past.
Perhaps the other option might be for the RAF to train its future ME pilots under the MPL scheme? But higher than present levels of theoretical knowedge would probably still be required; I once had a multi-jet student who claimed that he'd never been told that 86% rpm wasn't the same thing as 86% thrust...
