Interesting idea. I'm going to guess (along with Pekka) that the official line will be no.
However, there is a specific use case that this helps with. If you have a team of members with their own individual accounts, and all are on the same project, it stands to reason that they will naturally end up upvoting each other -- not out of malice or attempting to game the system, but purely because they're already on the same page, and will likely naturally tend to agree with one another's posts.
In that scenario, sometimes the accounts end up looking like sock puppets, even if they're not. As a result, mod action may get taken. So while I think that on the whole the idea is probably not going to be well-received, I can see it potentially alleviating that specific issue.
Of course, that assumes that this issue is actually widespread. My hunch is it's not, and that the downsides of doing this far, far outweigh this one positive.
