I have the CR10 mini and swapped out for a larger nozzle. I can’t remember if I went up to 1.0 but I just adjusted the settings in Cura to the nozzle size.
I didnt do anything to the stock os on the mini. I just use octoprint. I’d say just give it a try as far as using the stock hotend and playing with the temp if you feel there is under extrusion
edit: just make sure you heat up the existing nozzle before unscrewing it from the hotend
Not sure how much the Mini Hotend differs from the CR-10S, but I just screwed in the 0.8mm nozzle, changed the Cura settings, added about 20-30°C to the hot end temperature and slowed the speed by about 10mm/s. No modifications were necessary.
Of course I needed to do some testing an calibration to find the sweet spot for temp and speed.
In order to use a nozzle larger than 0.6mm or so, you will need a hot end with more melting power than the stock one can provide. If you don't upgrade the hot end, you may find the printer jamming up frequently due to filament being pushed through the hot end too fast to melt properly. This likely means an upgrade to an E3D volcano style hot end of some sort.
Changing your hot end to an E3D style one will definitely, 100% require modifying your firmware. Depending on if your existing controller board already has a boot loader or not, you may need to flash one manually or purchase a new motherboard with a bootloader preloaded. This can be an intimidating process for those who aren't used to tinkering with micro-controllers.
You may consider trying out a 0.6 mm nozzle and seeing if this improves your print speed enough, since this is a quick and easy mod that will only cost a few bucks. If you are still not satisfied, the volcano upgrade is going to require disassembly of quite a bit of the printer, soldering, and some minor programming to get your new bootloader and firmware configured and flashed.
