i am thinking to use a USB C connector to replace the docking connector. THe only problem i am seeing is soldering and able to send tx/rx and i2c pins, as usb c have 4 pairs of pins, 1 pair for power, 1 for data, 1 pair cc and 1 pair for sbu. as cc used for Power delivery things so that pair can't be used.

What you guys think? any input is welcome.
