It's possible, but not proabbly nor cheap.
Many fixed choke Remington barrels lack enough metal to use the Remchoke system. One I had done uses the old Truchoke system, aka .795"x44TPI. You might be better off picking up a Remchoked 1100 barrel and keeping your old barrel stock. It won't be much more expensive.
And, there's lots of utility in an IC choke.
