From a new pilot perspective, I think we need to go the other way. The multi-engine course is super short; it's basically an exposure course. 5 clearhood (basic aircraft handling) rides, test, 2 night flights, 2 nav trips, 2 round robins, 2 cross countries, final test. I have less than 50 hours multi-engine (plus 50 sim, you basically do the course in the sim first and then confirm in the aircraft). Everything else, I'm learning on my next airframe. King Air is under $2k per hour. Globemaster is 25x that. When I was in Portage, there was pushback from the OTUs 'cause too many people were sucking/failing; they wanted a 150 hour multi-engine course.
Right now, we already train at a pace that, by civilian standards, is absurd. 18 hours on the Grob (and by the end of it, you're doing loops), then right onto 1100hp of Harvard. 100 hours of that - covering basic flying, aerobatics, instrument (blind) flying, 500ft navigation, and formation flying - and then (in my case), you're on to the aforementioned multi course. So here I am, a winged pilot with 160 hours. 160 hours isn't even enough for a commercial pilot's license (the "can fly crappy bush planes" one, not the 1500 hour "can fly for Air Canada" one).
