  The spec sheet for this winch is 9000 lb max pull with a 178:1 gear ratio so removing the gear ratio would only give about 50 lb cable pull--this would give lots of acceleration but (I hope) is within human capability.
  According to the spec sheet it is a series motor so it cannot be reversed by reversing the terminal voltage. From the picture it looks like some sort of reversing lever going into the gearbox so if you bypass the gearbox you have to think about how you will reverse.
I think likely that 9000lb rated pull is at standstill so the 50 lb would also be at standstill and would drop off rapidly as speed increased.
There are a lot of "might works" here so you almost have to try it to see what happens;-- and you might not even need a speed controller!!
