Licensing - Can "Custom Morph targets" on a Metahuman Mesh be sold on the Unreal Marketplace?

Hi guys
I have a morph tool prototype in which I’ve included a Metahuman example with different Face Morphs.
Can I Sell the Morphtool with a Metahuman as a Example character with the included Morphs?

Here is an example:

Thanks for helping?
