I don't know that you will be able to use one of the old pbasic controllers without it's associated OI and radio modem. Unlike the current controller it does not have any general purpose IO lines that can be used for what you need. I think your idea of a microcontroller and a cpld to drive the LEDs is a good idea and will teach you alot about microcontrollers.

the SERIN command is exactly what you need.
I'm not sure whether or not it would be legal, but you could attach to the LED outs and use them to transmit parallel data. You would have to use one pin as a double edge triggered(rising and falling) clock. You would probably have to interleave data, so you would also need a start of packet signal line. The rest of the line could be used for data. I drew out a schematic one time. I will see if i can find it. Its probably gone. This would likely have too low of a data rate to be useful and has no advantages over reading the dashboard serial stream other than novelty.
I can't find the dashboard protocol spec anywhere on the IFI website anymore.
