That theory would require a kind of drydock / starting-gate arrangement, where you lead the saddled horse in at one end, the knight and squires climb steps to reach stirrup-height platforms from which they can respectively mount the horse, and work on bolting the armour into place. You'd need one platform either side of the horse so that one squire could hold the armour in place while the other tightens the nuts. There would be swing-doors at each end to stop the nag wandering off when it got bored with these antics...
Now that's a film scene I'd like to see, and then wait for the MOPs to ask if it ever happened!
As opposed to requiring a crane capable of lifting an entirely harnessed knight onto his horse, (which must for true comic effect be obliviously munching grass and unaware of the knight dangling precariously above him).
It doesn't really have to be a monstrous dry dock though does it? I figured more like a fenced pen with sides that the squires can climb on to help fix plates etc into place , kind of like the ones the Americans use for Bronco riding maybe?
Or simply a bigger version of the kind of mounting block that is occasionally found at stately homes?
A darn sight simpler than building a crane and a lot more dignified for the knight (more work for the squires I'll grant you, but who cares about them?!)
