No it is not an XY problem!
But it is.
You have invented a term, "reverse mosfet". That suggests a
way of doing something but is essentially meaningless as we do not know what it is you
really want to do and on that hangs
all the detail - because there are obviously
different approaches for different needs.
The important question which you have persistently failed to address is the need for isolation. If you need isolation, then an optocoupler is the answer and we move on to how this will be connected, whether it must reflect the AC polarity inversions or give a smoothed response and if so, with what attack and persistence.
If OTOH, you do not require isolation, then there still remains questions of which elements are common and what polarity is what.
The implication that there is a single component or a single process and thus a single answer is clearly time-wasting,
that is the
XY problem. Failure to pose a
genuine usage case is nothing more than trolling - as we now realise. We are no longer answering
you as it is pointless, but for the benefit of any innocent who stumbles across this with a genuine need.
