I wouldn't recommend it. It's hard to tell which ones you can and can't. Like previously stated, some will and some won't. Not all bearings have the same contact surface where they sit in the cups.
I honestly wouldnt do it. I mean if it seems like it fits and you put it in and somthing doesnt work right then it could get stuck. But thats worst case scenario. Just dont jam anything in together until your sure it fits right.
