If this is a newer minivan, it wouldn't be easy. Even with a donor van for the necessary parts, the power liftgate is controlled by modules on the bus and wiring that may not be there. The TIPM would also have to be reprogrammed to accept the new option.
I suppose that a factory lift motor and arm could be fitted and wired to a hard up/down switch, but safety stops and lockouts would then be defeated and you don't want that.
Braun (or some other upfitter) may be the easiest way to go, but it will probably be somewhat pricey.
