I don't see any problem with doing this.

An additional change to keep in mind is that this will involve the
iterators too.

Iterators (also for performance reasons) get a copy of the image 
OffsteTable.

If the OffsetTable is removed from the ImageBase class and passed
to the ImageRegion, the iterators will have to get the OffsetTable
from the region instead of the ImageBase.

That's not a problem at all since the iterator is constucted from
and image an a region anyways.  Good news is that only the base
classes for the Iterators keep these OffsetTables.
