James Goss said "there have been other future Romanadvoratrelundars (remember Paul Cornell’s brilliantly glacial flapper?)" in October's Vortex when talking about Tre.

So, the author who created Tre considers the official Romana III to be an "other" Romana. I think that's enough to say they're different incarnations, similar though they definitely are.
