Why Can't My AI Brothers Wear My Chapter Colors!

It could be super simple, just allow the AI Brothers to wear the Host's other Class Customizations.

For example: Lets say you are running a Decapitation Operation, and you're playing Assault bolstered by your AI Brothers Quartus(Bulwark) and Straban(Heavy). Instead of them wearing their standard Ultramarine Colors, let them wear the Host's hard earned Wargear, Chapter Colors, and DRIP! If a player joins or leaves, the AI replacing them can be using (essentially) the Host's other Custom Space Marines!

Perhaps the actual customization that gets chosen could be taken from one of the Host's custom saved sets for whichever AI(CLASS) joins in place. So then you could play Operations and have your own squad of Space Marines from a specific Chapter, or you could have a squad of Marines from random chapters if the host has different armor sets saved for each class.

This would clearly increase morale amongst Brothers Old and New by 200% allowing us to fulfill the Emperor's Will must more effectively.
For The Emperor!
