I have seen most of the answers to this question.  However, this may be one
thing you have not considered.  Remember TSM is only going to mount the
tapes it needs once you update the access to the copy pools so that they can
be used to resolve the restores.  It think your issue was you thought you
had to recreate the primary pools before you could do any restores, not so.
As one suggested you may still need to rebuild the primary pools in a real
disaster so that you can start running backups again.  You should probably
test that after you get your stuff restored.  Otherwise, you will only have
one copy of your data unless you have multiple copy pools until you do so.
Think about what you are trying to accomplish from a business point of view,
then whittle it down to something that you can afford.
