My cousin wears double crossdraw holsters. They're both canted to his right. He the right one just ahead of where a strong side holster would be and the other where a normal crossdraw is on the left. He stands at about a 45° angle to the firing line to shoot anyway so the right one is already downrange. He just twists slightly to pull the other. Give it a try before bailing on the idea but do it with two identical cross draw holsters (both canted left or both canted right, depending on which hand you will draw with) rather than a left and a right. All you need to do is make one holster and you're in business.
