I got a chance to swap the doors this afternoon
The old door came off really easily, with just 4 torx bolts and a pin holding it on to the roller brackets.
The new door went back on just as easily, propped up with some offcuts of wood while I bolted it in position.
It opened and closed fine and locked manually but I noticed it didn't lock or unlock with the central locking. A quick check highlighted differing electrical contact plates so I removed both old and new and was able to swap them over - fortunately they had the same electrical connectors - and immediately the locking worked again 😊
With the door hung I swapped one of the rear light clusters for a new one - the lens was pretty badly faded so the tail light was pink and the brake light was almost white
With the evenings getting darker I've just ordered a whole new set of bulbs front and rear after noticing the high level brake light was out along with one of the rear number plate lamps. I've gone with uprated halogen headlight bulbs that are apparently '200% brighter' without screwing with the beam pattern but we shall see 
I've still got a second pair of headlights in the garage that I keep meaning to strip down to paint the internals black (except the reflectors, obviously
) but I haven't gotten round to it. Now I've ordered some new bulbs maybe this will spur me in to action, it's a nice evening job so won't take time away from other projects 
She also needs a damn good clean inside and out
