Aye could add one per season.
Or in fact I'd probably pay a tenner for one as an add-on, like skins/bobbleheads, just an alternative in-game voice pack.
Arguably voice over is just cosmetics. A different voice for each ship would be pretty awesome, give each ship a unique personality.
Maybe Shatner would be Asp Explorer, or DBX. Brian Blessed as the Federal Assault Ship, Joanna Lumley as Courier?
I often use three or four voice attack profiles to give myself "Crew". If I have, for example, Astra as my main voice and going to a Haz Rez, I can say "Prepare for Battle" and another voice will take over while i am in battle, if I am entering a station i might have another voice to request docking and and talk while i am docked.
