I'd definitely like to go to this. Dave S and Little Robyn have given some excellent suggestions for local performers. Sticking with the NE connection, maybe you could also get Geordie ex-pat Bob Davenport up from London? Bob Fox (solo or reunited with Stu Luckley) springs to mind. And how about Anthony Robb on pipes? Carolyn Robson might even up the gender balance a bit. Also there are the various surviving members of Lindisfarne (and Maxie and Mitch, for that matter).

Good luck with this - it's a great idea. Should we bring our own lava lamps?
