Yes, this is a good idea.  I2C would add a second bus in addition to 
sysbus and could show the limitation of the existing bindings.

Several simple devices in such hw/misc/i2c-echo.c, hw/gpio/pcf8574.c or 
hw/rtc/ds1338.c could be converted to Rust in the same way as pl011 or hpet.

For now, avoid devices that have properties (e.g. hw/sensor/tmp105.c).

Block devices are substantially more complex, so I'd stay with something 
simple for now.
