Can after after-market customizations make a bioship even smarter than what you've described or is pig-level intelligence the maximum?

They'd be expensive, but yes. There are some wholly sapient bioships out there but they're rare. 
[i]Carnaval[/i] is a Lybarim bioship of roughly human intellect but it is chained to the will of its creator, keeping it completely loyal.
Winsome Yelena [i]was[/i] a human but had their brain transplanted into a bioship.
[i]Sseven[/i] is a bioship with a Constructed Intelligence housed within, kept under heavy observation in case of Rampancy.
[i]Big Wet Billy[/i] is an amphibious bioship with approximate brain function of a human six year old, grown by an eccentric Communer.

Are you looking for something specific? I can always make exceptions when they're interesting.
