Um, not if the lesser lens is closely approaching

the resolution limit of a digital format at a given

stop - there is no room for "improvement". In analogue

formats, this is less evident...

Yes. But if you took your better lens, and compared it

on VHS with a better-yet lens, you may still see the

slight difference - but if you compared all three

on the same digital format, with all else equal, and

with all lenses shot at the first diffraction-limited

stop of the least of the three lenses, I think you

would be hard-put to see resolution differences on

tape with these three lenses. If the worst of the three

lenses is diffraction-limited at a fairly wide stop

(say, f4...), then under many conditions, without

changing other things, I think you would not see any

difference in resolution... (see also the post above...).
