Use a fully delayed walljump to gain enough horizontal distance to place a bomb past the lip of the overhang. Unmorph to hover in the air above the bomb while it explodes. Ride the explosion into a down-grab to reach the ledge.

Use an unmorph bomb boost at the end of a mid-air SpringBall jump. Also requires a crouch-jump and down-grab to complete the maneuver. A spring fling can help add some lenience to the bomb placement and unmorph timing; it requires pausing early, before jumping, in order to be able to initiate another pause immediately before placing a Power Bomb.
