No it would not be.
1. there was few topic about that, and no.
2. try to play GTA: SA, RE, Quake or any other action game on your phone. its pain in the ass, and Soldat is Way more dynamic than that. so NO.
3. Android/iOS is different system than windows, so NO
beside did you tried Portal for SHIELD(Nvidia Android Console), its one worst idea to port dynamic FPS game to mobile device, even if SHIELD have joystick its still pain in the ass. and 98% of phones have only touchscreen, so BIG F NO. :]
Soldat its way too dynamic to control it using touchscreen, and its not so easy like conversion from PC->Console like making dumb AI, aim assistant and removing some options, its way harder.
