Integrate MetaHuman body with character asset for marketplace

Hello everyone. I am currently developing a modular character for the marketplace that is rigged to the mannequin but uses the body of a metahuman underneath. The character works well and is able to be animated using the mannequin control rig, plays default and custom animations just fine and uses the new mannequin rig IK system for limbs.

Now the problem comes in packaging. Epic states that there must be a single folder underneath “content” that contains the whole asset in organized subfolders.

My asset uses a metahuman head and modified body and these references the default metahuman folders. So the project is like this:

Content
–Metahumans
----common etc.
–ModularCharacter
----blueprints etc.
I tried to move the Metahumans folder inside ModularCharacter and the engine crashed because the PC ran out of vram. I also tried moving the folder and contents in windows explorer and all links were broken.
Any suggestions?
