Actually there is a model with refueling pods on wings that allow multi aircraft refueling. Pods have baskets for aircraft with probes, plus still has boom
I saw a C-130 refueling two Pavehawks (USAF version of the Blackhawk)using a system like that. It was south of Albuquerque, and Kirtland AFB has the Pararescue School.
I’ve never seen one, nor were there any at the base I worked at.
