Surface morph onto brep (made of many trimmed/untrimmed surfaces)

Dear Community,
I’m wondering if it’s possible to use the surface morphs functions for brep that’s made of surfaces (it’s no work because ‘fail to convert from brep to surface’ error)–of if there are any work-arounds

In my example, I get pattern on a brep and I’m want to edit them on the planes (I want to edit the flat versions)
The problem is, this no work in surface morph because brep cannot convert to surface (245.9 KB)
