(with a the right knowledge and tinkering talent)
It might even be possible to retrofit these to an existing none isolated supply ?

In case you missed it, the minimum order is 25 units.

Mr Orchid, are you watching?

Ummm.
That's pretty much what I was suggesting :o

Oh! SORRY! I thought you meant a rake of wall rats mate?

Or the one at

http://uk.farnell.com/xp-power/ie1209s/ ... dp/2536046

which is both reasonably priced and available immediately (although I've not checked the data sheet for any gotchas).

These would be fine for the lower powered pedals, but you might have to go up to a 5W rating for the greedier ones.

This sort of thing is used extensively in industrial electronics these days where odd isolated supplies are needed. Isolation voltage is usually 5kV or at least 1kV and they are usually S/C proof.

P.S.
Farnell often have a better range and availability than RS

Just because you know what I'm talking about, it doesn't mean I do!
