Haven't handled a huge range of folders so far, but my Dacora I is marked in feet rather than meters and has a coldshoe slot.
But a few possible flaws with it:
1. The door release is right in front of the very basic coldshoe, and might not be the easiest to work with your range finder if it extends forward any. [It is also only about 16mm front to back, whereas every other camera I have close to hand are 18-20mm]
2. My example of a Dacora I broke... Something is bent out of alignment so the body shutter button doesn't want to engage any longer. The springs and levers involved didn't look the most graceful when I got it, and kind of assumed someone tinkered with it to get it hobbling along again, but I can either have it fold or I can have it with a working shutter release, but it then jams up when trying to fold again. No clue if that is common old age damage or if mine was just specially damaged somewhere along the way.
3. Red window film advance.
But personally I wouldn't worry too much about what scale is currently marked on a scale focus camera. Careful application of something like whiteout tape or good masking tape, a metric to imperial conversion chart, and some care with a suitable fine tipped pen will make short work of any pesky metric markings if they're somewhere with enough space. Wouldn't be the first camera to get a modification to enable easier use by the end user.
