I'm considering using yeast (wyeast 1056) that's a year old. I've washed it thoroughly with sanitized water in a sanitized vessel before storing it in a sanitized air tight jar, which has been kept in the refrigerator for over a year (approx. 13-14 months.)

Anyone ever attempt something like this? What is the worst that can reasonably happen: perhaps yeasts that don't ferment, in which case I can simply go out and buy a new 1056 smack pack?

Do at least a two step starter with it. Yeastcalc can help you to figure out the size for the batch you'll be brewing.

Decant any liquid, starter and go.

I've used save yeast that has been a lot older than a year before.
