Attach activity to a second twitter account for the character

I do not like games or applications that litter up Twitter with content, but I would like to be able to follow the game through Twitter. To do this, I would like to be able to connect TWO Twitter accounts to the application: My own to be able to trigger game activity, and a second for the game to report character activity. Then, I could follow the account and even use it to interact with other characters without worrying about dirtying up my own timeline.

It would be important, however, to allow suppression of (or always prevent) Twitter handles from being used when publishing. I wouldn't want my conversational or attribution activity mentioning other people on Twitter to become mention spam to their account. That might be OK in situations where both people are playing the game, but otherwise it would be intrusive.
