Mini SPi Front Mounted Radiator?

My Minor is currently fitted with an Allegro crossflow radiator and electric fan that I fitted in the late '80's. It's worked perfectly but is now getting slightly old and leaky (like the owner) and I was looking for a replacement.
I'm considering the front mounted type from the very last Rover Mini's, it's a compact efficient unit and on the basis that the engine is basically the same in terms of water jacket it seems like a good option.
I realise I could go original but they are way too big and inefficient in my humble opinion.
Has anyone ever carried out this particular permutation and if so any handy hints?

You are correct in that the Minor radiator is much larger than required but the size is a left over from the days of thermo-syphon and no water pump.

You could fit a Classic Mini Cooper S which is smaller and therefore more efficient.

The Cooper S radiator was fitted to the famous Miller's Minor and proved very satisfactory as regards keeping the engine cool.

Hi Phil, thanks for the reply. I certainly can't see why it wouldn't work really well in conjunction with the Mini electric fan and expansion vessel.
