Could this be effective in addressing the vortices problem?

The attached longitudinal vortices are symptomatic of separated flow, just like turbulence. And like turbulence, once you have it, it cannot be 'mended.'
All you can do is 'avoid' it, or 'minimize' it.
An 'all-soft', radiused tail would 'avoid' it, but that conflicts with the 'door' situation, if I'm understanding things properly.
The only tool available for 'minimizing' it, is, to keep the slant angles 'small', as the vorticity grows 'geometrically' with increased slant angle. Very non-linear.
