Swap skeleton using blueprint

Hi, i’m currently trying to make a character creator where the character can have 2 or 4 arms
So i need a s rig that supports both while being efficient.

Is there a way to swap rigs using blueprint so i can change between a 2 armed and 4 armed rig when needed?
Or is there a different way to do this more efficiently, maybe attaching a second rig to a base?

Greetings,

You can actually carry out this operation outside ue4 and in the 3d modelling program. You can create a single armature (skeleton) and two meshes parented to it, one with two and other with four arms and switch between the meshes in ue4 while keeping the same skeleton and animations. Ue4 allows you to pick an existing skeleton during the import.

you’re right, however this leaves the extra bones in the skeleton which means it’s going to be inefficient.
i would need some kind of system that can actually swap rigs or maybe deactivate certain bones if that’s possible.
