Since nandsim announces subpages, UBI will use them. Except you define your own
VID header offset.
UBIFS does not use subpages at all and UBI only for VID headers to be more storage
efficient.

So, ubiattach -O should completely fulfill your needs.

If all other parameters of the NAND match, and I guess so, otherwise ubiattach
would notice, the UBI image should also work on the target.
Modulo fastmap, if you have bad blocks.
