I don’t know how plausible this is, but a way for trans men and trans women to exchange sexual traits. There might be an answer elsewhere in that there are animals that can change sex in certain conditions so there is some biological evidence of possibility in a singular case. However it seems anti-poetic that we have genetic females who want to be genetic males and genetic males who want to be genetic females and the answer that we currently have as society is for them to go fuck themselves.

I guess for more realistic, then deep dive VR.
