Looking for help to create a 'Preserve' UVs' function

Hello guys,

as mentioned before I am also willing to pay someone who can help me with this problem. I try to create a function that allows me to adjust vertices of a mesh while preserving the given UVs.

I explained my desired result and current progress in this thread: Preserving UVs while modifying vertices

I would be really grateful if someone will get in touch with me.

Thank you!
