I think having a minion of your player character is a fun idea, BUT I would say it would have to be very simplistic, especially compared to say, the Y'shtola or Thancred minions. My recommendation would be to have a base for each race that's only really customizable in terms of hairstyle and colors. And also limit the outfits to AF gear or something that's equally universal; it wouldn't be reasonable to expect every armor set in the game. In this way you could make it of your character or a friend's, and you could name it. Like it'd be a "Wind-up ______" and you fill in the blank. There'd probably be a surprisingly high amount of work to make it happen though, so who knows if anyone at SE would even go for it. But I think it'd be cool, and I'd buy one.
