Turn them into a mini raid. Switch from farming trash on a timer to increasingly difficult 5-8-10 min boss fights. They give similar reward as mythic raids, then why not. Not saying it needs 20 man style complexity, but 2-3 phase bosses with 3-5 mechanics and weekly m+ buffs designed around them, like cloning: every boss duplicated. Or hardmode: +1 random mechanic to every boss
ps: there you go. but not i am the one who gets paid millions to come up with ideas. So cut back your disgusting arrogance and style next time you talk to me
