Cross-live

For example, there apparently is a clinic in Canada that makes people crosslive for a year before giving them hormones!

Although some of these subjects were lesbians inclined to cross-dress and to cross-live in order to cope with social prohibition of woman-to-woman sexual relationships, it is likely that at least some male-identified subjects who were biologically born as female had come to realize a psychological transgender male identity.

[Transgenderists] will probably, although not necessarily, cross-live (see next section) and/or take part in hormonal therapies that would cause certain sex characteristic changes.

I also don't consider Transgenderists to be a different creature from a Transsexual -- I consider the two to be two points on a spectrum. Some people can get by with crossliving, while others need to take further steps.
