Teleflex Gauges

I have a 2002 SN closed bow, the teleflex gauges are starting to fade and I am looking to replace the gauges, I bought the replacement kit from nautique parts but did not know until I received the kit that you had to drill a hole in the hull, that seems a little extreme to me, Is there anyway to utilize the pitot tube setup that it has with newer GPS gauges or any other pitot tube utilizing gauges? I know I wont find any gauges that will plug into the existing plug that connects to the gauge from the factory, but theres gotta be some gauges that I can change up the wiring instead of drilling a hole in my perfectly good hull. Please let me know if anyone has a solution thankyou.
