A big No! from me on this.
That will just make it easier for the Borg to swallow base after base and move on to the next one.
It gives a hugely outnumbered country a small, yet distinct chance to recapture a base. Of course this only works if the original captor doesn't choose to defend what he just grabbed, a phenomenom I often withness with smash&grab hordes off all countries, particulary the ones avoiding combat on the way.
