Hi Aram The bad news is that if you attempt to change encoder you will find the motor will no longer work. The good news is that you can simply add an encoder somewhere in the drive chain and EMC will be pleased to use that rather than the motor's encoder.
There have also been a bunch of patents issued and reports released of projects that multiply the pulses from an encoder. You might dig a bit and find such hardware/software schemes. Be sure that you put the multiplier after the motor drive rather than between the motor and drive.
