.idk if this is possible to do but what if one were to get a AR15 in the .22 LR and take its lower off and get a 5.56 upper ? Would those two coincide?

no it won't

Unless a company specifically says so I don't think it would work without being dangerous.

Why don't you buy a AR in 5.56? Then buy a .22lc upper for it or a .22lr drop in conversion BCG?

A purpose built .22lr like the M&P most likely will not pin to a mil-spec AR upper. If the rifle is built as a conversion the lower should be a standard AR mil-spec receiver. Best to check with the manufacturer since its your face in the danger zone.

Edit: .22lr upper
