OOMIS!!! They actually did that, some time ago. 2,000 years ago to be exact. There’s a gemarah somewhere that says in the time of R. Yochanan, Kedusha was so great, boy and girls would play together and not sin. So I guess if you consider us just as holy, it would be no problem. We’re holier than Rishonim, Achronim, Rambam, Gra, Chasam Sofer etc.
However I have a gut feeling that we ought to follow the plan and bidding of the Master Planner, ?? ????? ????? ???? – ????? ?????. I think one of the early poskim explicitly write ???? ???? ???? ??????. HaShem know the psyche of BOTH versions of humans, He knows best how to keep them healthy (and holy). Apart.
