Your condition for circling approach is erroneous. If you are on instruments at 1000ft. and stabilised you are in a position to continue on the existing runway. Any change at that stage being in IMC should lead to go around. Assuming that you are visual at 1000ft and asked to side step just disarm APP, FDs OFF, select bird and set RW track, turn and align with the RW. ILS frequency is locked below 700ft. If you have already prepared secondary for side step by selecting only that RW you can activate that, otherwise it is too late for head down work.
