Actually in recent years, there are many people who argue exactly that.

Their claim being that taking medication to suppress testosterone and boost estrogen, as well as having various cosmetic surgeries (castration, inversion of penis, bone/cartilage/soft tissue reshaping of facial features), gives these males a "female body".

Some of these males even claim to no longer be trans as a result of these surgical and pharmaceutical interventions, referring to themselves as "cis women".

That entirely depends on whether one considers "woman" and "man" to be social identities that anyone of either sex can choose to adopt.

Many people don't accept that belief, for a variety of reasons, such as viewing that belief as being based upon sexist stereotyping of women and men.

Instead, they understand "woman" and "man" to be the words used to describe, respectively, female and male people who have reached adulthood.

From that perspective, a "trans woman" is simply a man (male) who desires to be a woman (female).

Having some brain measurements that are more similar to the opposite sex correlates with homosexuality, not trans.

The initial studies on this didn't control for sexuality and mostly used subjects who were both homosexual and transsexual. In later studies that also measured sexuality, no correlation of sex atypical brain measurements with trans was found, only with homosexuality.
