But Monster Hunter has a certain identity and I wouldn't want another action spinoff to lose that identity.
In the context of my proposal, which states that the handheld games would remain unchanged and the game would be handled by the DD/DMC crew instead of the MH devs, I'm kind of left interpreting this as "I'm worried that, if this hybrid was actually successful, it would kill the classic series in the same way that RE4 killed classic RE."
I don't think that would happen here. Japan is still very into the MH series as it is. This idea is focused primarily on appealing to the rest of the world, for whom the series's incredibly dense mechanics (combined with being tied mostly to handhelds) has made it very unpalatable.
If you didn't like it, you and everyone else who adores MH as-is can go straight to the next traditional handheld iteration.
It's not obtuse though, it's just different. You simply can't play MH the same as every other action game out there, including Dark Souls. And the sooner you realise that the quicker you'll enjoy the combat in MH.
"It's not obtuse though"
"TBH I don't think the demos or even 20 hours is enough to wrap your head around the controls let alone the entire game when it comes to MH."
By your exact parameters, it is absolutely obtuse.
