You can change the belt etc without a locking kit, provided the cams are aligned before you take off the old belt. If you are careful, it boils down to taking off the old belt, replacing the pulleys and tensioners and putting the new belt on. Provided it is still aligned then there should not be a problem.

That sound feasible if the cams didn't move on the valve springs. But they will. The plastic cam lock will hold both cams still relative to each. 
Surly you can cut the old belt in half, longways while still fitted, then push on the new belt and simply cut off the old one, everything should have stayed in place... 
This sounds like one of those ideas which, because it is so blindingly simple, nobody has ever thought of before! (So long as it is only the belt being changed - and none of the rollers etc.)
And that's where the Devil is in the detail! It is rarely that the belt needs changing purely for itself, but far more likely the belt tensioner bearings are worn or the roller bearings are noisy, & it's recommended that the waterpump is changed as well as the roller & tensioner when the belt life (40K or 4 years) is reached, and Vamps idea would not be workable in that scenario unfortunately
.
IMO, I also think you would have a B* of a job getting a new belt to stretch enough to fit without getting some slack from the belt tensioner? :-/
