65 Dart Wagon Conversion to a Sedan Delivery

I thought I had a Mopar Door Ajar light but guess not so looks like it will be the original plan. Now I have to find a suitable spot for my Rear Window Switch and Driver/Passenger heated seat switches. A friend said move the radio to a housing under the AC vent box and add the window and heat seat switches where the radio would be (already cut out for the radio, which would mean some metal repair grrrr!)
Would it be possible adding a small console under the dash just for the switches!
