The "some pages being unmapped" part is unclear. I assume what you mean is "possibly resulting in a partially mapped source folio, which is undesired." But there is also the problem that we could try collapsing a folio to a same-sized folio, which doesn't make sense (assuming the folio is fully mapped). Clarify all that, please.
