A/C Retrofit for Cherokee Six

Does anyone have information regarding the feasibility of retrofitting
air-conditioning into a Piper Cherokee, possibly a 6/260? I live in
the southeast and would be flying toward Florida where heat and
humidity are a real challenge much of the year. A/C is one of things
that my wife would consider a must in any aircraft we were to
purchase.

And as long we are talking about Sixes, I would appreciate any
opinions regarding the pros and cons of the club seating that is
available in some planes.

Thanks in advance for any help.
