CAN/j1708/j1939 all in one chip?

Does anyone know of an all in one chip that can speak all the major vehicle CAN protocols as well as j1939 and j1708?
The ELM 327 covers CAN nicely but lacks support for the others. They have a few other chips in the 32x range but none that can do all.
I contacted them about it and they said there wasn't enough room on the die for everything. Bummer.

DIY on an MCU.
Most of the protocol bits that you would need are available, the rest as either a free registration, or an NDA away.

Yeah but that's a lot more work than I'm wanting to do. Many of those protocols have different baud rates anywhere from 9600 up to 500kbps.
Getting the protocol specs and writing the application is about 90% more work than what I wanted to do intended.
The ELM327 does everything I want except J1708.

Ok just found out that an ELM 327 is a PIC 18 series chip with an application on it.
