Check out TRP HY/RD brakes. They're hydraulic, but cable actuated. You'll also need a short pull adapter for use with your mountain levers https://www.amazon.com/dp/B073CCKD85/. Your stock discs are 180mm.
Okay I just built some thing like this, the cables and housing issues I have solved it by running continuous cables and housings where there are no exposed cables for the derailleur, this eliminated the requirement for cable stops at chain stays, the shifting is crisp and I haven't faces any issues.
I have used road shifters on an MTB wheelset and cassette, most of them are cross compatible provided it should be same speed with some tweaking to the RD. I ran this set up for roughly 600 kms with out any issues. If your MTB had 10 speed cassette use 10 speed road cassette it should work. The problem you might face is indexing, which is pretty easy to solve by adjusting your high and low screws on your rear derailleur.
Problem would be the front derailleur you might have to get new shifters compatible with the triple chain rings , if you're changing the cranksets from 3 to 2 you might have to get new FD. There are ghetto hacks to over come this issue by going friction shifting, there are shifters available to meet this criteria ! Checkout gevenalle shifters which might make this a possibility. I went old-school and got myself a downtube shifters. I have indexed 11-40 8 speed cassette and 9 speed DR and friction shifting for FD. This set up helped me have different combinations of friction and indexed shifting I can go either ways on both FD & RD.
Lastly,on braking if you're going mechanical disc, I guess there wouldn't be any issues if you get the gevenalle shifters they make one for all kind of brakes , if you want to use a specific set of brakes like the 105, you might have to tweak your braking by installing these JJBP Short Pull Conversion Brake Arm Set for TRP HY/RD https://www.amazon.com/dp/B073CCKD85/ref=cm_sw_r_cp_apa_i_L12hDbJ3D2359
which is the most cost effective way to over come the pull issues.
Hope this helps !
