There is a Map-to-BMP program by Punt floating around which converts maps into UO Landscaper format. I'm not sure where my copy is at the moment but someone might be able to provide a link.
The only shortcoming is that it won't support the newer Mondain's Legacy Map0 size. But you can use another utility by Punt to convert the old Map0 size to the new Map0 size (the utility inserts blank data in the extra space).
I've found UOCopy to be buggy when copying from certain areas (try copying certain statics from Ocllo). However there are a few other options to copy between maps. Some of the newer versions of Worldforge have a map copy function. I believe that Punt's Worldmaker allows cut-and-paste and copying between maps. Also, I think TDV Mulpatcher also has a map copy function.

Worldforge for POL (custom for POL servers, but has map copy function and other useful updates):
