I had thought of that earlier as a possibility, although Eric Hamp doesn't mention the Latin form in his discussion of the etymology of feam 'sea-rod, tail etc' as far as I can recall, if Mod Ir fimíneach is connected to OIr feam 'rod' then of course it is also coonnected to all the other related forms of the feam-lexeme in Modern Gaelic dialects, feamachas 'disgustingness' feamaire 'a prick(?)' none of which are particularly positive.

DIL does have 'femen', apparently from Latin vimen, a flexible rod, e.g. a willow wand used in basketry.
Perhaps 'fimenach' is the substantivised adjective:
'vimen' > 'fimen-ach': 'highly flexible one'. That would do for hypocrit.
