As to riding it on your Bike Friday PakIT or your Brompton, that should not be an issue if both bikes fit you well. For my first four Randonneuring seasons I rode all my brevets on a Bike Friday Pocket Rocket with 20" (ETRTO 451) wheels and my first brevet ever was a 300 km, because I signed up too late in the season (by then the early 200s were already full). Even my first successful 400 km was on the Bike Friday. People have finished PBP on Bike Fridays before.
Most likely you'll have a more limited range of gears on those two bikes than I had on the 3x10 BF Pocket Rocket, but it all depends on your legs and what the route is like. I have since upgraded the BF to 2x11 (Shimano R7000) and have the exact same gear range as on my big bike, the Elephant Bikes NFE, just not as much choice on wider and/or more supple tires.
