ORANGE LACKEYS: Whenever Larfleeze would be dealt damage, you may deal up to 3 of the damage to a single adjacent Orange Construct object and then remove it from the map.

If Larfleeze has some way to reduce damage (say, toughness via a Hammer), can you combine it with orange lackeys?

Mastermind and Imperv don't stack so I can't see why those two would.

The thing is that Larfleeze's special is not listed as being Mastermind. So, you might be able to stack a damage reducer with it.

Any damage not dealt to the construct is still dealt to Larfleeze. Thus, Larfleeze could use powers that reduce damage on the damage that is not sent to the construct.

With normal mastermind, all the damage is transferred to the fodder with none being kept by the masterminder, so the masterminder couldn't use damage reducers.
