can a F100X be converted to coil?

You could get a Vanilla coil of either recommended or one higher than recommended spring rate (since you don't have the assist coil on the damper) and just drop it into the air spring. There might be an issue with the air piston, since it is plastic, it might not stand up to the coil in the long term.

Your better bet would be to get the negative spring assembly from a vanilla and the vanilla left leg top cap (spring preload), in addition to the spring.

If you experiment with the F negative spring assembly and top cap, you might end up with an air assisted, coil sprung, hybrid.
