What I do is put the ePub into Calibre, convert the ePub to ePub, pull the subsetted fonts out of the converted ePub and replace the fonts in the original ePub with the subsetted fonts. Then I fix the OPF & CSS if any of the fonts were deleted. Then I have the subsetted fonts in the ePub without it having been converted.
