I doubt that would make any substantial power compared to how much it costs. The only way I could see that making good power is if the intake mani/TB/intake setup was very restrictive. An NA motor can only suck in so much air.

if you've got the $$$ to toss around on that kind of setup you should just save your pennies and get a quad set-up WITH A MANIFOLD. if you run the straight-joiner type of manifold you're not going to have a very streetable car...not to mention the other mods required to run such a set-up.

Maybe i'm overthinking the system, but couldnt you fab up pipe as follows...
Large Filter-->MAF-->3" pipe-->Y split into 2x2.5" pipes-->one to each throttle body? I mean technically the same amount of air would be drawn in as 2 separate pipes, and you could still use the MAF then. Kinda like those stupid twin intake filter setups, but reversed. 1 filter, then split to 2 intake paths.
Either way this is a lot of work for what would seem to be not huge gains. Seems like everyone who goes for power on NA does it for the sake of being the person who made a lot of power NA. When i was a member of the DSM boards people were goin for crazy setups on the 4g63NA motors yielding some power gains, but the cost per power was so extravagant. I can understand people saying "yeah well i dont wanna go turbo because turbo has a lot of hidden problems", but weighing out the amount of fabrication, tuning, and time you have to put into NA to get 30whp you can get that out of a 5psi intercooled setup and have a car that drives just like stock with minimal fuel management upgrades, virtually no added fuel map tuning, and less chance of things breaking.
Long story short, i applaud the inginuity and creativity of people going for crazy NA upgrades, but i'd rather see my money go to power

a lot; however i would rather have that set-up than a turbo.

i would like to see a left side intake system i think it will make it easyer to put a turbo on it because of the piping
