From what i have seen with my test, it may just not be possible due to the way MVAM sets itsself up for the ships, example, you start out as CGIVoyager, right, Open MVAM button, choices: Deploy Aeroshuttle, Get on board, or Recombine. If you deploy the aeroshuttle with out getting on it, then everything is reversable, but i have found that if you deploy the AS and the MVAM AI activates the Holoshuttle, then you cant put the areoshuttle back. Its kind of like using any MVAM ship, activating it, and then beaming/Transporting to the other part/s, then MVAM wont work until you beam back, the option is there in the MVAM button, but i just wont function.
on the other hand, lets say you "Get on Board" and take the aeroshuttle out, then in the MVAM option, the choices are: Aeroshuttle, Holoshuttle, or deactivate. There is just no option to redock to Voyager.
At this point i just dont think its possible with out some minor script tweaking at the very least, though i admit that this was a hastily put together test, and im going to do another more comrihensive, but im not hopfull at this point. But still i plan to use CGIVoyager along with the areoshuttle to make a MVAM Voyager, with Holographic ships like in the episode "Basics, Part I" when Voyager fought the kazon!
Im also going to try changing some of the names in the MVAM scripts to see if that helps, well see!
