Ameyam, I have done exactly what you are proposing: mixed digital and analog on this exact plane. I'm using the standard sized Tower digital TS126 on the rudder, 2 Hitec 225mg on the elevator, and 4 CS12 analog minis on the ailerons. I have 35 flights on mine already, and love it! Have not noticed any aileron "blow back" on high speed passes or any other issues.

That being said, I've had almost a dozen Hitec 225mg's, used in various planes, and have had at least 4 of them go "bad". They either start jittering/not centering, or quit altogether. I may swap my elevator servos to something else before long. I also was going to use the Tower TS110 digitals on the ailerons of this plane, and 2 of them went bad during installation/setup! Not impressed there either....
