Very easy as the system doesn’t rely on the unreal skeleton.
You would just have to setup 4 equipment sockets. 2 for rings (if you want to keep equip-able rings), 1 for main hand and 1 for the offhand on your skeleton.
The actual equipment setup for skeletal meshes happens in the EquipmentCharacter blueprint. It has different skeletal mesh slots for equipping items and replicates changes to other players and syncs them to animate with your character. The only issue would be that the demo equipment items are skinned to the unreal skeleton. But they are just demo items and meant to be replaced anyways.
