Please support Wan2.1 - MoCha ~

### Feature Idea

[ Wan 2.1 - Video Character Replacement ]

MoCha: Based on Wan 2.1, it's a simpler and easier-to-use video character replacement model. It's more user-friendly than Wan 2.2-Animate. Simply mask the character in the first frame to replace the video character, preserving the original frame's dynamic lighting and shadows.

Since it's also the base model for Wan2.1, I believe you can easily support it. Thank you~
