In theory there is the infrastructure to modify the nickname within ffado. 
There is also a cli-tool to do so I think.
But not all drivers support this either because the devices don't support 
nicknames, don't have a documented api to change the nickname or because we 
didn't implement it yet.

I am all for "use nicknames instead of guid" in the user-visible parts. Maybe 
the nickname-collision can be circumvented programmatically by appending a 
number to the additional devices found with the colliding nickname just within 
ffado. Or append the guid on the colliding devices nickname.
Or register all ports with several names: guid_port, nickname_port and 
devX_port (if jack supports more then two names per port).

Have fun,
