For anyone interested here's a follow-up to my question above. I misspoke
and said my Jeep has an overdrive. I was referring to the torque converted
lockup. The answer to my own question is yes, you can mount a switch to
turn off the lockup. You will not overheat the transmission but you will
get a check engine light after a while and the code will tell you the lockup
is not working.

In my case, rather than install a switch I had a local trans shop change the
speed the lockup engages from 34 to 45 MPH.
