I actually think this is an awesome idea that works out really cool because it creates a pattern:

S1 - Mando-focused
S2 - Mando/Boba
S3 - Mando-focused (which would be the rest of the regular Mando S2)
S4 - Mando/Bo-Katan

So, cutting movies from these would work really well with that as well:

1st Mando movie: Mando: lead
2nd Mando movie: Mando/Boba: co-leads
3rd Mando movie: Mando: lead
4th Mando movie: Mando/Bo-Katan: co-leads

I’d love to see an edit of this. I really think you’ve glommed onto the perfect way to handle this all now.
