Be careful what you wish for. Actually I can see no 'Technical' reason why you couldn't add 2 x 24mm together or any multiple of 12's and 24's - As long as you have no issues with seal integrity. The raw material is available to go thicker, but the cost is logarithmic not a logical progression.
You may still have mechanical problems to deal with - long enough mounting bolts for one.
A couple of basics that are worth thinking about. As your intake trumpet increases it's length (call it runner, whatever - my background is with mechanical injection on race trumpets) your torque does increase as the column of air entering the system is longer. The air column develops more 'momentum' so to speak. It's less prone to 'flutter' and other types of air turbulence. This has the nett effect of increasing how much air / fuel mix winds up in the cylinder for compression.
There is a down side. It narrows the rev range at which this peak torque is developed. As with anything that has more 'momentum', it's harder to move that object in a new direction. The air column doesn't accelerate as rapidly. Your nice flat torque curve wil become lumpy. That's ok if you have a nice close ratio gearbox to keep the engine singing at peak, but less useful on the street.
There may be ways and means around it. Higher stall torque converter. Lower ratio diff etc, but bare in mind - the huge v8's with mountainous tunnel rams make huge power, usually at 5000rpm (or some other equally stupid number for use on the street).
