Making a compact board based off of the ION with a built in 24/48 fader system would probably sell to high schools. 512 outputs (one full universe), make some slightly smaller ML encoders and put them at the far right of the console (faders on left), and make it small enough to fit in to a cramped HS booth and easy enough for a teacher to turn on and bring up a fader. I'm sure that the idea of a modular console is daunting to some teachers, and 1000 output parameters seems like an overwhelming number.
Make it so that someone who really wanted to do lights could use the ML section, have keypad access to a full softpatch and effects section, but also make it easy enough for a teacher to come in and use a restore disk after the show to call up a default patch and sub set that is made during the install.
Basically, I think that no HS console should be without 24/48 operation if they have a 48 rack. With a full universe of outputs, you could fit 10 moving lights at 30 channels each if you wanted to. But 20 channels is more realistic for MLs that a HS would get. So, that leaves you with room for the 48 or 96 rack that they'd have (anyone with the cash to get a 144 or 192 rack would also have the sense to get an ION), as well as some LED pars, fog machines/hazers, and DMX toys as they come along.
So basically, re-make the express and base it off of the ION platform, include a 24/48 fader section that can all be swapped to subs, and put the ML section off to the left in order to reduce the console depth so it'll fit in tighter booths where it's sitting on the little shelf that was built behind the booth window for the old Lightronics, Leprecon, or NSI board that was in there first.
And if the ION is priced so low, this console should list for $2800 and go for $2200.
I'd say 48/96; plus, two universes. Any HS with MLs is most likely to run one universe to conventionals, wherever the hell the dimmers are located, and another to where ever the MLs would go. At minimal extra cost to ETC, schools will save money on data runs. Two universes, and you're golden.
