Sunnysky x2212 motors are great, Im getting 12 minutes of flight time with 3S 2200mah lipo on a tricopter of 650gms, and 23+ mins on a 2s 4200mah lipo with the same prop you intend to use.

Try to keep the auw below 2kg, ideally between 1.6 to 1.7 kg for a highly athletic hexa.
And try to start with a lower capacity lipo, 10000mah would be overkill, since you would also be increasing the weight which will reduce flight time.

Yes its doable, but I think you will overshoot 1.8kg with a short margin though,
and also these motors are available locally at quadkopters.com
