I also saw that cura isn't compatible with 1.75 mm material filament.
That's not correct there are tons of printers with 1,75mm filament and they all work fine with Cura.
I think I haven't understood the problem. You have a printer with 1,75 mm filament, then you also have normally a printer profile for it and if not you have to create one with the custom FFF printer. There you should have the filament diameter and there you set it to 1,75.
So in my opinion you don't have to touch the material profile, you have to tell Cura that your printer is using 1,75 filament and that is done in the printers profile machine settings.
The E values in a gcode file are in "mm of filament" and the diameter determines the area of the cross section and so determines the volume of 1mm of filament. 1.75 filament is 2.405mm³/mm and 2.85 filament is 6.379mm³/mm. A big difference there and you would severely under-extrude if you sliced for 2.85 and printed with 1.75.
I think you can create a custom material based on a generic material. Then you can change the diameter. @Smithy and/or @gr5 will know how to adjust for that. Another option might be to switch to Volumetric extrusion (but I'm not an Ultimaker guy and I could be wrong about that).
