2) would it be possible to use the FRAM+DIP adapter solution and get rid
of the battery altogether? It is not clear to me if this could be used
on the low serial scopes also. Same goes for the programmer mentioned
before.
I do have a 2465B with a FM16W08 FRAM and so far it has worked perfectly for several years. Plug-n-Play without any special mods or anything else but to mount the FRAM on an SOIC to DIP28 adapter, and copy the NVRAM data into it. I used the GQ4X4 programmer, that is compatible with both the FRAM and the original DS1225 NVRAM. I ordered the FRAM, NVRAM (150nS version), the low profile DIP28 socket and the Aries adapter all from Mouser back then. Last time I checked some months ago those Aries brand adapters (very good quality) where getting low in stock and prices had skyrocketed to something over $63 (!) for one piece, which is about triple what I paid back almost 3 years ago.
