I'd have to double check (I'm sure someone will tell me if I'm wrong), but I don't think you'd be locked into a widebody preventing you from going 767 IND if one is open on the next bid. If you take the MD as a new-hire, then a bid comes around and you can hold 767 IND, you can bid it and be awarded it. Now, since that is a lateral, you'd be locked into the 76 for 18 months, which I'm sure you don't care about since you live there.
