Me and my friend have been going back and forth about this possible play. Here is the situation:

                              You are the away team with two outs in the bottom of the ninth. Bases are loaded and it is a full count. Are you allowed to pull the catcher and put him in the infield as a fifth infielder? If I am correct due to a runner on first you don't have to worry about a dropped third strike. You see managers pull an outfielder and put him in the infield all the time but never do they pull a catcher. Is there a rule that I have missed that does not allow the catcher to be put in the infield? I'm sure the home-plate umpire wouldn't like it but what do you think. is it against rules?
