Intake idea

Having 2 air filters will actually help filter the charge air more effectively. You would essentially double the intake filter area by 2 thereby dropping the air velocity through each filter by 1/2. The slower the air flows through the filter the more effective it is at filtering the air. Also the pressure drop through the filter setup will be lower than having 1 filter since drag force varies with the square of air velocity which could net you small gains in hp. However the merge of the 2 tubes could possibly cancel any gain from the increased air flow.
I just want it for looks, filtering capacity is a plus

You would have to relocate the radiator resivoir tank, for enough air to flow through the hole on that side. In my opinion, two filters would probably hurt performance. Seems like it would also disrupt the airflow when joining the two pipes into one, making it much more turbulent. 
If two filters were beneficial, I'm sure aftermarket companies would have made at least one like that. I'd listen to Gernby, he really knows his stuff. If I were you, I'd just buy a nicer intake. Although if you really want to make a custom one, I say go for it... but I would make one with just one filter. But hey, it's your car man. Do what you want to it, you can always change it if you don't like it.

The Y pipe would effectively shorten the intake length, which would change the torque curve. On the S2000, intake tube length has a very significant impact on performance, so you would need to do quite a bit of testing to figure out the right layout.

All of the super clean bays I see remove as much as possible. I feel like adding another filter and tubing that looks kinda odd isn't going to make the bay look cleaner. Just my opinion. Do what you want.

I don't hate the idea from an aesthetic point of view. However I question the symmetry you mentioned. If the throttle body was centered, then sure, but it's offset to the right. Having the intake bend to the left makes sense from a symmetrically balanced point of view.
Again, though, I like the idea of the look and, with careful design, might prove interesting. I hope you are able to punch out the numbers and prototype it. I'll be curious to see results.
One thing is for sure, if you got it working with no loss, your car will stand out!

The S2000's motor isn't even limited by one intake filter. Adding a second one is pointless (especially if it's sucking up hot under-hood air). You only really see filter setups like this on large V8s and V10s which move a huge quantity of air.
