The problem with that however is that the plane will no longer fly with the typical characteristics of previous 737s, so what will happen if pilots lose control as a result? Remember, they're trained on typical 737s, then potentially fly a plane with differing flight characteristics.

I bet they'll be willing to roll the dice since the differing flight characteristics are in a narrow regime that no pilot should find him/herself in to begin with. Until the last year or so our simulators couldn't even accurately duplicate how the airplane will handle up near the edges of a stall, so it's not like we're particularly familiar with how the airplane handles in those situations anyway. We're just trained on how to recover, which is the same process regardless.

I agree that three AOA vanes would be better, but financial considerations still drive the process to a large extent, and I'll bet Boeing gets away with the fixes they've already implemented. We'll see though! With Covid-19 my airline is just trying to stay alive, let alone figure out when they'll get their 40 MAX airframes back. :(
