Was gonna reply to you on the post about JumpStart but by now it wouldn't really be seen by that many people and I figured a few more would want to see this, but I threw together a roster for the JumpStart X PBS Kids crossover idea. I went with the idea there being duos, with both sides having an ally. I tried to find fitting counterparts to the JumpStart cast, so in terms of PBS Kids I did have to make some tough cuts (sorry, WordGirl, maybe we can try to shoehorn you in to DLC later). The PBS side is also more "modern-aligned," realistically they'd want to go newer I guess, but there are still some surprising choices, I hope. Here is what I came up with in the end:
