What it comes down to is the training aspect. Regardless of the age it is always cheaper to have the same family of aircraft. Ex any 737 starting from -100 all the way to -9. A mechanic or pilot will only need a little bit of training between aircraft. Technically speaking you could actually group the 757 and 767 together as they were built on the same platform per say. Going beyond that, if you really think about it, the design principals are really shared with all families of aircraft with the same manufacturer. In the end, an all Boeing fleet versus a fleet mixed of Boeing and Airbus, the all Boeing fleet is much cheaper because you only have to train maintenance on one companies aircraft.
To be honest, you really should group in that way, by manufacturer rather then by family. The expense would come in when you decide to have many different manufacturers.
