Hello,
I want to use a normal propeller as a counter rotating propeller. Can I do that by fixing it to the motor reversed? Basically, I want to use a normal propeller as a pusher, how can I do that?

for pusher config, u can use normal prop, with smooth side out wards and reversing the rotation. For electrics i have used this way many times.

The prop number should face the nose of the plane(just like pushers) and the motor should be reversed.

Okk... Thank you sir... I will definitely try that. Will that effect the thrust produced? Or will that heat the motor?

it wont heat the motor at all(only if it gets complete ventilation).
and it wont affect the thrust produced

best of luck
