That's a pretty scary but brilliant idea, in my personal opinion. So which one of you gets the credit for it?
Call me jaded, but FIRSTers are driven by awards and recognition. It's in our blood (though we don't like to admit it). What happens when both of you go after the same angle on your Chairman's application? Unless the rules change, only one of you can get the credit for it.
True, if any team was to break the glass ceiling of "no teams beyond 200 have ever won the Chairmans Award", it would be 254...they definitely mirror the resources and support of a pre-200 team. But if one of you wins with it, the other team needs to find another angle to take next year, because that idea is now "old hat" to the judges. And knowing FIRST teams (for the most part), once an idea is recognized, all development on it ceases - because it has served its purpose.
I think inter-team partnerships are great...I used to do it myself. But just as in those old movies with the business partner running off with all the money, things like that happen today, and a team who you thought you knew may not be one who you knew at all. And no, I'm not saying that against either of you in particular, you both are outstanding teams, I'm saying it because you just need to be sure you trust the team you're collaborating with.
As for the collaboration aspect, I honestly would be terrified if all 16 Delphi teams had the same game design (or any multiple of teams, for that matter...I'm not just picking on Delphi

). Especially with their game experience, if everyone did this, it would stifle the rookie retention rate. I can absolutley see it turning into leagues of teams that "acquire" younger teams into their pipeline or shutting out teams that they didn't like. And I honestly don't want to see Dean take up an SEC role.
Please don't get all upset about my viewpoint - it is only a viewpoint, and its not an angry one, just something from an old FIRSTer who's been through the trials and tribulations of collaboration and who cares about both of your teams.
