Mix Shimano Deore derailleurs with Microshift shifter for Shimano I have Shimano Deore derailleurs 3x8 and I am thinking about upgrading my system with a combined shifter/brake system, such as Microshift's SB-R483. Microshift themeselves states that this system is only compatible with Shimano Claris 8 speed 2403,2303,3303 derailleur system. 

However, half ignoring their statement, could it be possible to use the SB-R483-system for a Shimano Deore derailleur? Doesn't Shimano have an internal standard for the derailleur system so that a Shimano compatible 3x8 shifter fits any Shimano 3x8 derailleur system. Any experience or superb technical knowledge?
The stumbling block is that while Shimano mountain and road rear derailers used the same actuation ratio and were fully cross-compatible until the start of 10spd mountain, the front derailers have always used a different cable pull. So if you have a mountain FD as well, you'll probably find it's impossible to get the front shifting set up for no chain rub anywhere, and shifting performance won't be very good. There are many questions here that explore options in this scenario.
