You might be able to accomplish the same thing with one of these, depending on where the "top tube" meets the seat tube:

Thanks for the clarifying photos! My BF completely lacks that welded-on tab. The "seat" tube nearby is also ovalized, as well. That derailleur mounting adapter will need some modification, if it is wide enough to fit around a the tube, in the first place. I suppose I could make arrangements with ha more local builder to add such a tab. I am always stunned by how light this folder is when compared to other folders- I just wish I had a little more range on the gears.
