Have you tried pushing the oil up from the caliper with a syringe, worked on mine although mine is standard. Might be worth a try
Or leave it to stand for a day or two sometimes works.
Good luck.

might be your master cylinder, sounds like its either got air trapped or is not travelling enough to bleed properly.

could be the m/cylinder ratio is wrong for the new calipers.
