Sounds like a great plan! Do you have your eye on any other jams? I'm entering the Dungeon Crawl jam with a friend toward the end of march (their first time).
I have a couple of other things cooking for potential jam entries.
I have one eye on this jam:
https://itch.io/jam/themed-horror-game-jam-16
Need to dig into the rules, but If I am allowed to work with what I already have to build something new then I may enter that with a small project.
It would be much less devTime than "SMILE" as I am using Smile to build out a reusable library to move between projects as I go.
I am also looking at:
https://itch.io/jam/panic-game-jam
The reasoning for focusing on "horror" for now is that I think you can get away with a lot of janks and it's quite a popular genre and a bit easier to approach than others.
I also feel like I have a lot of relevant research and planning I can apply (notes on mechanics, mood boards, film research, etc)
However, I am also working on a deliberately "anti-horror" project in the background for a bit of a laugh/break and palette cleanser between serious dev sessions.
If you are interested in maybe teaming up for one of those jams or need some input/a team member for your jam at the end of the month let me know.
I can't commit to anything immediately but If you are interested I am sure we can find a jam that suits us both in future.
