Oh, you should :D It's fun to try new things. I was thinking about 'we' and something like Star Trek's Borg would fit: we are the Borg...or the auditors, from the Discworld, for whom individuality is fatal and thus must speak as 'we'. I suppose letter writing on behalf of a company could work; we are pleased to offer you the position.
I'll be interested to see what you come up with if you do tackle it :D
