I think it’s a cool idea but I also know that the nacelles have a safety function of containing the rotor blades in the event of disintegration (e.g. from a bird strike).
If these fans have blades with anywhere near the same kinetic energy, I would be nervous.
Southwest 1380[0] is a case where the cowling didn't quite contain the thrown rotor blade.
They were very lucky that only one person died.

Turboprops have already existed for decades, so perhaps you should already be nervous.
