isolating pollen from 2 males for 2 fems in same room

I have 2 separate males and 2 separate fems all in bloom at the same time.
I want to breed two Bible gum lemons together and I have a buba lemon I wish on the gsc girl.
The bb lemons are from seed I bread by shaking the male lemon production strain over the 2 respective fems.
I'm brainstorming putting bags over the males b4 collecting the pollen then tossing the dads or catch the male flowers just b4 they burst putting them in a jar till they do and separating the males b4 they burst . I could separate the males in a separate closet for a while under weak CFL but I worry they would still cross pollinate as the bloom rooms in the room the closets in. I also worry they will not produce for me that way and frankly I don't want to clean out the closet.

You could get a small tent to use as an Isolation chamber.

No room for whole tent but can do boxes. Actually oldmeduser suggested taking cuttings and putting them in boxes with CFL on a shelf. But now that you mention it I have one box that will fit a whole plant . So taking both your suggestions.
