Hi Nige,
Spoke to dad tonight and he's suggested Metro Turbo springs as a possible alternative to Cooper S springs. Sizes will need to be checked however!!!
I had a quick look around on the web and threw these up which may be of use however.
Without double checking sizes I can't confirm either way atm but I'm sure you can do that bit quickly enough

Alternatively, he said check Kent Cams. I looked quickly and they do 2 different sets of double springs for the Mini - VS-2 & VS-39 - which may be of use. Again without checking sizes I can't say for sure!
If you still need help feel free to drop me a mail and I'll try dig some more in depth
