Depends on the overall resistance and coil mass of your build whether or not 50 watts is enough.
That being said, you can absolutely build a quad coil atty that capes the way you want within the limita of a 50 watt device, you are just going to want to use a light gauge wire to keep the mass down. Four two ohm
coils will give you a half ohm atty, given the output range of a 50 watt mod this should give you a good range of voltage adjustment to get the coils reacting how you want. For quad coils at 50 watts, 30 and 32 awg kanthal are appropriate.
