Intriguing idea.

Looks like no for now.  I did put 30 mins or so into pulling the 2d window components of the CS Civa out of the L-1011 and putting them into the CS 727.  But it looks like the XML code is tied into variables from the panel code of the L-1011 and the Civa won't power up or allow any keypresses in the 727.

They'd have to make it more general.  Right now it's a L-1011 thing and I suspect that's the way they want it.

A lot of research might turn up the values to set to make the Civa think it's in an L-1011, but I don't have the time to put into it.
