Current round-trip records for MR and MT are supposed to be around 3:10 .. 3:20. A well-acclimatized and prepared hiker in good shape with a lot of trail-running experience can certainly do it 3x in one day via some combination of MR and MT, as long as it's warm and the trail is in a good condition.
EF is a different story, it's up to 5.7 in difficulty, it will turn away most people capable of sub 8 hour MR and MT, and the idea of speed-climbing EF just seems stupid.
I don't see why the participant would need 3 permits.
What kind of support would be useful? If it is attempted by multiple hikers at once, I'd park a few people along the route with food, water (gatorade/heed), extra clothing, walkie-talkies, possibly some dexamethasone. The biggest thing you need to worry about is that an exhausted participant succumbs to AMS or twists his ankle during the third ascent, after sunset, and no one finds out till the following morning.
