The Ecotec development would be accelerated and sent to charm school.
Interior improvements get highest priority across the board.
Buy one of each of the top 3 competitors in each segment. Force the divisional management to drive each one for a week and write a report on what GM could do to beat each car. Those reports would be reviewed by the product planning committee.
Continue to refine the 3.4 DOHC until the Shortstar arrives. Use that engine in place of the 3800 where it will fit (it's a physically large engine). Shortstar replaces the 3800 and the 3.4 Twincam company wide upon arrival. All other pushrod V6es dropped, replaced with heavily refined Twincam/Ecotecs.
Atlas I5 and I6 programs changed to allow for use in full size trucks and cars. Specifically starting with the Holden VY platform in 2000. From this point forward, the Holden V-platforms replace the upper end W and G bodies.

Dealers would be Chevy independent, Pontiac/Buick/GMC, Oldsmobile/Cadillac. If you look at my lineup, each dealer would have access to every platform in GM's stable except the ones at the extreme ends of the spectrum, yet there isn't much overlap.
Chevy handles FWD "everyman" with some RWD sports thrown in.
Buick handles FWD traditional premium, Pontiac handles RWD "everyman"
Oldsmobile handles FWD "euro" premium, Cadillac handles RWD world beater luxury
