It would be 61.65. It only says you must hold at least a current PVT certificate. It doesn't say it can't be a 61.75 certificate. FSIMS goes a bit deeper into adding additional ratings on a 61.75 cert. You would still have the FOREIGN BASED notation but if you complete the normal training and checking for an additional rating it would be followed by U.S. TEST PASSED.
If it is allowed then what would be the path to get the UK day only restriction removed, remembering that there is no FAA night rating?
There isn't any. Since as you point out there is no FAA night rating there is nothing to add. It's been suggested a foreign pilot could complete the 3 hours and 10 landings required for a PVT cert and then get a 90 day student night solo endorsement.
