It is a good idea but, logisticly, I can't see it working.
For instance my Sidey is currently 160LY away from me, after travelling that distance I would then have to try and navigate (in an unpimped Sidey) from there to the location that everyone agrees to fight, then fly back to where I have parked my Cobra, and do the 160 LY trip back to Sorbago, where I am currently trying to do my bit for the Empire.
Until there is a "Drop Off" service available for collecting parked ships it seems a lot of effort for a couple of hours fun.
