The seeker, the element class cruiser, the modified free trader/far trader are all examples of that classical Traveller trope - ships that don't use the rules as written. They join a long list of ships that ignore rules as written at the time.That's the idea I was going for... Increase everything in the engineering section.
In my own games, I rule zeroed the restriction out of existence, provided the refit made sense within the existing deck plans.
Then I discovered that they altered the internal bulkheads on the Type-S when they converted to a seeker. Apparently they did it to make the engine room more spacious, and they just didn't need that ship's locker anymore...¯\_(ツ)_/¯
Personally I do what you do, anything within the hull can be moved around, drive rooms expanded at the cost of staterooms or cargo and the like, bulkheads moved.
When I saw the TNE covenanter (the frankenship scout/gazelle) I photocopied every CT deck plan I had and started cutting them up along bulkhead lines and the like to find other combinations that look good.
Weld a few small craft to an x-boat, stick a Safari ship onto a subsidised liner, all sorts of wacky designs can be made to fit
