Thanks for the responses folks! The outer diameter is 36.5mm (measures with a caliper) so I reckon it is doable. I think perhaps a drill would be best but as you most of you say securing the frame would be expensive. I guess I may just have to bite the butting and find some 1 inch forks, until I can find a way of doing this effectively.
Fucks sake, a frame builder has answered your question and strongly made the case that this is not a good idea. But hey ho... at least this level of Darwinism may be of benefit to the gene pool.
