Flipster, my dear boy! It is with great regret that i must inform you that such an onerous task would indeed be within the reach of the humble J. It would be beneath us but we could it. Sorry
I'm rather taken with the idea of putting the Mk5 wings onto the Mk3s - now that would be a farce multiplier
In fact, as a deal-maker we'll throw in the urinals too. Pop em thru nav training and away you go - we'll even pop back on a regular basis and top them up
