Would it work if it gives more movements than the normal movements of the ship?
Yep. When you pop the pod, you can get 7/2 movement, or 11/6, whatever.
If you go into combat, however, you will lose any movement over the max, and will leave combat with at most, one less than your max.

Just give the ships a space yard with zero production rate.
The only problem is that the ships can then retrofit and scrap & stuff. If you only allow it on capital ships, that's reasonable.
