My idea would be observing that Woodbine just bought the neighboring tower at 1845 Woodall Rodgers, which was an early local example of the parking podium tower (floors 9-17 are office, but below that its windows mask a garage). So make the first three or four floors of this site along McKinney something really special.
Then, because there are no tenants to block across the street, get City permission for the parking deck to form a ceiling for the streetfront retail that is architecturally tied in to its design. Think a Texas modern Sistine ceiling that actually spans the avenue at levels 5-8 -- continuous with 1845WR's existing decks 5-8.
1845WR could have the portion of the very large ninth floor amenity deck that falls on its property, and a negotiated portion of the new spaces in the connected garage, while the new tower has the rest.
