[OT] Increase torque on DC brush motor

Hi guys, I'm sorry if I'm off topic you can delete the post if it not useful for the community. I want to ask a stupid question from a noob like me.

If I have a brush DC motor, in my case a MY1020 500W, is it possible to increase torque of the motor, in particular stall and low rpm torque (high RPM are useless in my application), replace the magnets with a greater number of it and with a strong performance material like neodymium?

I think that now are in ferrite. The number of teeth in the motor are twenty and magnets are four.

When I add more magnets, for example the same amount of teeth, I need more brush element or the actual number, in my case four, are enough?
