Denis, as a Scot and a Yorkshireman (and latterly a Frenchman) I can't see the point in going to a load of expense rebuilding an engine (2 or 3brg) if all you're going to do with it is to shove it under the bench, just in case. If you're not going to use it then it seems to me at least a cheaper and easier option just to keep the spares, and should the day come when the car needs a fettling, to do it then.
One thing to bear in mind is that whilst the 3 bearing engine has shell bearings they are inherently weaker, crankshaft wise than a 2 bearing engine and need to be line bored in order to prevent deflection of the centre bearing under load. Not something you can do on the kitchen table. Talk to someone that knows before you go down that route.
A full engine rebuild can cost considerable amounts of beer tokens, which ever option you choose. Don't bodge it. Do it right, do it once.
