What if Dr. Watson’s other grandchild was a psychologist?

‘Take the red pill…’
Oh boy. I just had a really cool idea: with Portia Adams the consulting detective now operating from 221B Baker St, how cool would it be if her cousin, another grandchild of Dr. John Watson, was a criminal psychologist?
I like that idea. I’m trying to work out if this new addition to Portia’s life should be a man or a woman. Regardless, there are all kinds of opportunities here for conflict, tension, competition, emotion… the list goes on and on.
This is a story after all, and I personally LOVE it when a character links to another character from canon, it’s like an inside joke between the author and I.
I have to think about it some more, but I had to write it down cause I haven’t stopped smiling since I thought of it.
NB: Just a quick edit, I wanted to make sure it was feasible that a woman at this time could be a practicing psychologist, and yes, it seems the first woman to earn a Phd in Psychology was Margaret Washburn, and that was way back in 1894, a good 30 years earlier. Margaret Lowenfield could serve as a good model for such a character.
