I'm afraid Leonard is completely right when he says

I may have made it sound a solvable problem as at first I only thought about
the difference in byte ranges. Unfortunately XAdES signed attributes and
PKCS#7 signed attributes with the same contents give rise to different hash
values, so there definitely is no way to make the transformation.

In that case you had better reject that project.
