Are you intending this to draw in air for the TMIC or an intake?
Before you cut into your hood, you should know that a lot of engineering went into the current ducting system, and it works very well for it's purpose. A lot of people smarter than I about fluid dynamics and airflow have discussed this and pretty much universally agreed that unless it was quite large, a hood scoop is going to provide inferior airflow to the TMIC. The main reason is that the current duct opening is located at the highest pressure area on the front of the car--directly on the nose. A hood scoop, though it may have a larger opening, is in a much lower pressure area, and will generally see poorer airflow.
If you're going FMIC or plan on using it to draw air for the intake, proceed. Though, I have to imagine re-purposing the stock ducting would be very effective at providing cool air to a SRI.
