From your other thread:
Sorry, but you're worrying over nothing. Put the filter on the lens, the hood will fit just fine.
FWIW, for both the XS-Pro and F-Pro mounts, in all the sizes I have (58mm, 67mm, 72mm, 77mm, and 82mm), the outer diameter of the filter is the same as the outer diameter of the same-sized lens cap. If the hood fits over the lens cap (it always does), it fits over the filter.
