Indeed. There is something that would need changing other than just graphics though. (At least if you want to make it a proper conversion.

-First, gravity needs to be turned off. Unless you just put all the fights in low orbit, in which case you can leave it on (and thus also leave lifting parts in). The idea for the latter is "you are not actually in orbit, but rather are just hovering at an altitude outside of the atmosphere."

-If you go with the "low orbit" thing, then lift needs to be notably more generous, since presumably a ship will be destroyed when it falls down below the battle area.


-If you go for zero-G instead, then maybe just replace the lifting parts with Life Support parts that, if enough/all destroyed, cause the crew start to die. So instead of weight, you now want a certain amount of life support per volume and/or crew number. End result is that you still want the parts in your ship, and they just do a DIFFERENT very important thing. Could also then add an expensive crew module variant with mechs/droids/robots that are immune to lack of life support but otherwise function the same.
