Going from a high kv to a lower kv with the same voltage will give you less power. voltage times amps = watts. With a lower kv motor, you'll be pulling fewer RPMS which means less amps which means less power. Electric motors produce 100% of their torque throughout the whole power band, so a slower spinning motor doesn't always mean more torque.

Sticking to the same motor and gearing down will give you more torque. Also, going down in KV with more voltage will give you more torque and more power overall. Going from a 2 pole to a 4 pole motor will probably give you more torque.

Going to a lower kv motor (same voltage) will give you less power, cooler temps, less torque, and less top end. It might help your setup as it will be a slower spinning motor, but in the end I would just gear down with the same motor.
