Yes, it would. It's not impossible, just difficult.

Well, merging the two would actually be rather a simple task I think since
you would still keep each md mode a separate module, the only difference
might be some inter-communication call backs between LVM and MD, but even
those aren't necessarily required. The prime benefit I would see from
making the two into one is being able to integrate all the disparate
superblocks into a single superblock format that helps to avoid any
possible startup errors between the different logical mapping levels.
