Ballistic Parachutes

Does anyone out there in 'Coupe land know of  any Ballistic Parachute Systems (or Ballistic Recovery Systems -BRS) that can be installed in an Ercoupe whether by 337 or STC?  Particularly as I'm hearing of more and more 'Coupes with wing spar corrosion issues, I'm thinking I'd like to have a system for my little bird.  I wouldn't think it would be hard to install a unit since we have those nice large rear windows that a system could launch through and easy access to structure below the floor and seat.
