In my view, promising coaxial motor without gearbox must not contain unreliable moving contact node.

Two motors are not the problem, because this increases the thrust twice.

I think that for example on the basis of two motors AX-1304N (http://www.hobbyking.com/hobbyking/s...Motor_7g_.html) it is possible to try to create a coaxial motor with weight about 12...14 grams for working with props about 8 inches.
