This is what I am using in my current campaign.

I checked the source of every mod (I use) to see if it should use either '+CarryableCharacterGroups' or '+CarryableCharacterTemplates'.

Not fully tested yet on all mods/enemy types, as I just started a new campaign and fixing my mods/settings while I play it. Let me know if you found issues.

reached character limit, so I created a gist here:
