Yeah as much as we'd like to take it as easy as possible next year, that's gonna be difficult. After the Spirit Bomb we're gonna need to take the both the Saiyan and Human facing stewardship actions, we will need to explain ourselves to both sides here. Berra is probably going to be running interference for us as much as he can, and people are going to be distracted preping for the invasion, so there will be some relief.
Also I see Kakara as leveraging the idea she talked about when gathering energy, the "Together we are strong" sentiment, to try and push for peace with Aramaians and Tastreyan, and lay the groundwork for a possible peaceful solution with Tamar's people. We know from the scouts that they are refugee's not a proper invading army, and there are large swaths of land that no one uses. Its a long shot, but better to try and fail I think.
Also....school....holy HIFL but, I have NO idea what Karen's school situation is going to be now, I've never gone to school with Saint Princess God-killer She Who is Going to Lead our Armies against the Invaders, so I've got no frame of reference but aside from the MIsfits who already know us the rest of the school has got to be some level of weirded out.
That on top of visiting Jaffur and shoring up our Style training, also I'm not sure we should train up Spirit Bomb more at the moment, its very good at what it does, but I can't see it being super useful against Tamar. Also it would definitely blow our cover as Saiyan's or at least decedents of Earth if we have to use it, I can't imagine the Spirit Bomb and Goku are separable in the context of the Legend's about it.
Also forgot to add, I'm still against Sealing the Dragon into Kakara. Just on the grounds that she doesn't need MORE action sinks. I still think ideally we'd seal it in Maya, give her a nice power-up and a story arc to follow that not just "has a crush on Karen". But I think that unlikely to happen, otherwise I'm still for just making our Dragon tiny and gaining a Team Mascot character for the Misfits while we slowly work to Diplomance him until we ether turn him into an friend or he dramatically betrays us and escapes.
