Flashing single variant firmware to a dual device?

[a.panda]

I tried to search for the topic but couldn't get a definite answer - is it possible to flash the G8341 firmware onto a G8342 device? I expect the SIM2 function would disappear but I do not use it. Will the SD slot still be readable, and are there any other lost functions?

I am on trip to Hong Kong and here the only variant they sell is the dual-sim G8342 and I will be flashing the single-sim UK EE firmware. I am weighing up options to see if it is worth buying.

I have flashed older devices many times FYI. Cheers!

Or, is it possible to extract the OEM.sin from EE G8341 firmware, and flash onto the customised HK G8342 firmware? Would I get OTA from EE in the future?
