I'll also welcome (and encourage) the comments of some working managers out there that have gone through this.
Let's take a look at both roles individually. Since you're on ERO, I'd personally push towards electronically dispatching the work. There's a lot of fears out there about this, because of some nightmare stories. Let's just say that it does work - you just can't believe the DMS vendor that tells you that you can set the system up on autopilot and walk away. Nor, can you believe those that say it can't be done. Every shop is different with strengths and weaknesses - so it needs to be set-up and controlled differently. For instance, one of the big problems with the ERO dispatching are techs working the system to assure they get dispatched the gravy they want. This can be somewhat avoided by having the foreman/advisor position dispatching the work by tech - instead of into a pool from which to draw.
With the foreman role, I have also seen difficultly with having a single foreman across multi-franhises because this person is often called upon to be the technical expert in all things related to those lines. It gets too confusing when you add in four franchises. The main purpose, normally of a foreman, to improve efficiency is to remove some of the admin duties from the techs (like searching TSBs and calling Tech Asst.) If you found someone that could handle all lines this might be possible - but it isn't typical.
More likely structure for shops in your position would be to go with franchise teams and assign a lead tech to handle both of these roles.
