I think that's an excellent idea.
Firing a continuous string of data that you *do* want isn't going to work in the long term over any non-clocked serial interface, particularly if the distance involved is non-trivial. You have to allow for cable capacitance and random glitches introduced by the environment so a proper, frame and checksum system is very important if you want reliability - even if it has more overhead.
The MATH CRC function can be used to get a CRC checksum of a set of data.
If the distance is short then it's better to stick with I2C or SPI really, even though they are unbuffered. They are both clocked and are designed specifically for this purpose.
