Pollen from a reversed female is female genetically, and all seeds from it will be feminized. This would be true even if the reversed female was from a regular strain. If you reverse a regular female, you will get regular feminized seed. You can't make males from female plants, period.
If you are careful, pollen will not get through the house. By careful, I mean do you best to prevent pollen from getting air borne in the first place, and keep the pollen plants as physically isolated as possible from any potentially receptive females. I keep the pollen plants small, don't put them in a tent, and surround them with an air barrier that keeps air movement off them. They only live long enough to shed some pollen, then I bin them carefully.
You are likely doing a larger plant, want to keep it in a ventilated tent, as well as for far longer than I do to let seeds mature, so your results might vary. If I was trying to do the job the way you are planning, I would trim the plant aggressively to open the canopy, and don't use a fan to move air in the tent, just use the extraction fan, and arrange incoming air to not blow directly on the plant. The key is to keep the pollen from getting airborne if you can. If you have the option of exhausting the tent outdoors rather than in, that might also help.
By placing only one pollen plant with your female, all seeds (or at least virtually all) will be a single F1 cross, so you will know what the seeds on the female plant are, and any seeds off the pollen plant will also be identifiable S1's. Ditto the seeds from the selfed plant in the isolation tent.
So, if you set things up with one of the pollen plants isolated as you describe, you will have 3 strains of seeds, all identifiable with reasonable certainty. Much better, IMO.
Good luck with it.
