A buddy and I are looking into building a few intakes like with this in mind...

Single plate base
Plastic runners with different lengths 3" to 8" that pull in and out of the plenum and base
Plenum slightly larger than stock plenum with ports on bottom using the stock TB or aftermarket ones

Basically its an adjustable intake that requires a screwdriver to tune.

What would you be willing to pay for it / want to pay for it.

Cool part about it is the base is the same no matter what, and were looking at doing some really cool designs to bolt on to it after that. Sad to say, yes it is not 100% performance oriented in the other designs . However the base model is all buisness, tune your runner to within .25" by just switchin them out. And since the runners are polymer you can dremel them a little for that little extra if thats your thing. And we have it all figured to use the stock fuel rails and stock throttle body, minimizing your cost. And to change your upper intake system you dont have to unbolt the fuel rails .

Some of the others upper intake designs are...

-Ultra Low, 1"-3" LT-1 type intake
-X Runner, high velocity runners with special plenum
-Spiderweb, how would you like your EFI Chevy to look like its carb? (Uses new TB)

So again what would you pay for the base pack, and then what would you pay for the extras?
