hi! as far as i know, there havent been any mentions of alternate routes yet, but it may be a possibility someday in the future (the devs said that they want to wait until OL:N&F is further along in its development before promising any more dlcs).
however, if you wanted to have a route with Baxter, there is a completed dlc for him in the first game, Our Life: Beginnings and Always! (aka OL1) the mc does not meet him until Step 3, but they can have a romantic (or platonic) route with him if they'd like to :)
**this also means that Baxter probably won't be getting a second dlc in OL2, since it would overlap with the first game's potential storyline
