So the political correctness types at Marvel have ruined Thor. He's becoming a woman in the future. Why not make Freya and Sif to be men too? One more gender bender, I guess.

Here's the thing: a talented writer might pull it off. Neil Gaiman in the Books of Magic has the old DC character of Doctor Occult
transform into Rose when in Fairie.
So it's possible for a character to be both, but this just seems weird with a Norse god of thunder. Dr. Fate writers had a similar idea back in the nineties.
This is a stupid idea that only the best of writers can pull off without it being merely as comedic and campy as female impersonators.
