Who knows? I do recall Watanabe was chief director for Space Dandy and Kawamori had the exact same role for several Macross projects, for example, so I'm under the impression that said staff position seems to imply there's more input involved than just being a producer who gathers a team and sits back. I'd also expect Taniguchi to direct and/or storyboard a few episodes.
In any case, the actual concept sounds vaguely like Patlabor on the surface, though it probably won't be exactly the same in the long run. Still, it's interesting enough for me. I'm also glad that Nakagawa is back as the composer, since he's been a longtime associate of Taniguchi and I like his music. Hard to tell how Active Raid is going to feel at this point, but it's definitely a little silly to see some folks randomly expecting something like Code Geass from that synopsis, even moreso when Taniguchi's directorial career has displayed way more variety than that.
