The delay relay boards could work. I guess its a little like reinventing the wheel 
Here is teh same thing from a US seller

As P-Wave said, you would need 2 of them and a 3rd plus an extra switch for service mode
 
Turning off the key is not a really great way to stop it in an emergency
 
the Autotop DIY costs maybe $15 and takes maybe 30 minutes to build and install 
To stop or manually operate the top, you just press the existing switch
 
I forgot that Tom had bought the Robotop company
 Robo-Top, One-Touch Convertible Top Module for 996 Cabriolets and 986 Boxsters, Convertible top module for Boxster and 911 Carrera! 
Its $79 and a 1 minute install plug and play
 
the Autotop DIY is basically the same thing, just not as compact
