You incorporate him in the MCU either by having him explicitly jump universes or by slotting him in and pretending he was always there, maybe with him making reference to it (people already joke that the ship in Deadpool 1 was a downed Helicarrier from Winter Soldier anyway).
You make him PG-13 by explicitly and cartoonishly censoring him and allowing him as the 4th-wall breaker to react and comment on it. Like literally throw a giant black censor bar on him and have him pick it up and throw it at someone's head. It's silly as fuck but it'd be a way to retranslate the hyperviolent absurdity already present.
