With "more integrated" you mean a breakout board
or similar for that purpose, right?

I know there are several breakout boards for the
various CAN Bus Tranceiver chips available online,
like for example for the Microchip MCP2551.

Just google for CAN-Bus (Breakout) Board and you
will find a number of those.

Best,
Herbert
