I'd replace all the cockpits with smaller windows so I could get that early-mid 20th century / Millenium Falcon / Empress Marava glazed nose look for my ship. I'm sorry if anyone disagrees with me, but that's just style.
I'd replace most of my video indicators that just display text with banks of Nixie tube displays, again because that's it's awesome. And of course, at that point, I'd also install a small fan (metal cage and all) to keep the now significantly warmer cockpit cool.
Paint it pink, lower it, and add a bouncy air suspension for those long stop lights.
This reminds of a game that I was in so many ages ago that the GM who ran it has since passed away. Once he asked us what we were going to do during Jump.
Of course, me being a munchkin back then (sadly in some ways, I'm not much better now) and some other characters went down the usual: "I go practice skills" route. It's sort of depressing prosaic of me now that I think about it.
Unlike me, one of the players was a really inspired fellow, and says he dons a spacesuit and goes outside of the ship and starts painting a mural on the outside of the hull, using an unused inflatable fuel bladder to make a "tent" on the hull so he doesn't see jump space.
To which the GM asks him, "You realize nobody is ever going to see that mural since the ship is in deep space."
And the player answers: "No, everyone will see the mural. Every time the ship is landed or docked a space port, people are going to see my mural. Even a week-on-week-jump, a trader like this spends more than half of its time docked or landed if you include yearly maintenance."
Had this look on his face like someone who was seeing a movie or a television for the first time in his life and liked the idea so much that other merchant captains were inspired by the unusual vessel and started painting murals on their ships and it became a Thing in that TU in that area.
