You can reduce the insulation in the wall providing you "trade off" by increasing it elsewhere ie roof or floor but if its a cost saving exercise rather than space saving its a pointless exercise.
NEVER push the insulation in all it does is to knock off any snots, then you have a cold bridge and somewhere for water to track across the cavity. Had this on a number of jobs, walls ****ed in whenever it rained.
