The ORD IFL has showers.
Since the OP will be in ORD for 6 hours, I suggest that s/he first try the IFL. In fact, the LX lounges might not even be open that much in advance of the LX flight. (Which might be useful information to have in case the IFL lounge personnel attempt to shoo the poster away.)
I would also to get into the MCO RCC with the F tickets. The worst that could happen is that they say no.
