This should be possible; however, it will require setting up the Rendering Settings to support Mobile Devices. Additionally, the Shaders themselves may need to be tweaked quite a bit.
I’d suggest starting here Mobile Rendering Features | Epic Developer Community (epicgames.com) and doing some research along with testing via mobile device debugging/bridging as well to find out what works depending on your character’s complexity.
This guide here Rendering Optimization for Mobile | Epic Developer Community (epicgames.com) may also be useful perhaps for optimization.
