Well, looking at ly/engraver-init.ly, you are likely missing out on
\consists "Font_size_engraver"
in your context modification. Alternatively, you can do its job by hand
and set
\override InstrumentName.font-size = #-5
Since the PianoStaff is basically a StaffGroup, it does not have much
use for a Font_size_engraver. The context setting fontSize is more
intended for the stuff above and below staves.
