I suppose it depends on how lubricated the seals are / age / state of the pistons. I think in your shoes I'd lubricate the pistons (red rubber grease) in and out a few times until there is easy movement, with either the pads or a block of wood in place. When there is easy movement and while still on the car press the pistons out about 1/2" so you have a surface to work with. Using duct tape as protection from scratches, then try to turn the pistons screwing outwards as you turn with some kind of polygrip. If no movement back to lubricating, pressing in / out until such a time as they will move. Clamp or block the hoses and remove onto your bench.
Or someone else might have other ideas ...
