It may turn out to be a cheaper option than an Mcas fix, who is going to trust the fix without a lot of testing.
A further idea is modify the engine air intakes to reduce lift at high AoA.
Boeing changed intake shape to increase ground clearance so why not to reduce lift, with Delta fins may solve the problem and it looks like re certification may be cheaper.
Perhaps make them elliptical in the vertical plain may work.
