Going to be a big disagree from me.
Making this a position that gives anyone those powers would discourage people from joining the team given the added responsibilities. Additionally, if existing infrastructure team members were grandfathered in, there could be some serious concerns associated with that. The diversity of the team is what draws certain people to them since the ability to "specialize" in one department is what they actually want to do.
You would be merging departments which, speaking from experience, is not a fun time to gain questionable results.
