If I ran Dodge there would be the large two and four door Charger, a smaller and lighter two door Challenger, a Miata fighter and a Hot Hatch. BEV, PHEV, V8, I6 and 4 cyclinder power. I'd hire you two guys and we'd all be out of a job in 24 months with Dodge in bankruptcy.
FCA US, had a Miata fighter, an actual Miata with the Fiat 124 Spider. The car would have made an excellent Dodge. I think the Italian brands (Alfa and Fiat) have failed miserably in North America and I laugh at how much the company waste to keep those two brands going here. They could have easily, badge-engineered those vehicles and supported the Chrysler and Dodge brands better, with additional low-volume products.
If I ran Dodge right now, here is what I would do. Return to the drawing board and forget about eliminating cars from the lineup, like FCA US did other than the L-series. Dodge needs a compact street sedan like the Neon and Neon SRT-4. Design a baby charger and fit it with a 1.3-liter turbo and the SRT with a 280-horsepower 2.0-liter turbo. The reason why the Chrysler 200 failed, was because FCA US put all of this engineering into the car, like AWD, and state-of-the-art autonomous parking and whatnot. But people who buy compact and midsize sedans, don't want fully loaded cars; they want something fun and reasonably priced. So, there are no fancy leather seats, no 900-watt sound system (a simple 500-watt one will do), and no need for a 14.3-inch screen and a passenger screen. Build a sharp-looking compact sedan, focus on build quality rather than NVH scores, and make it fun and affordable!
Next, the Hornet will not be successful in North America, unless it isn't built here in North America. I would reopen Belvidere to create the Hornet, next-gen Compass, and the new Rampage there. The Hornet isn't a bad vehicle, but due to where it is built, there won't be enough profit and availability to justify it past its MCA (mid-cycle action) or "refresh."
With the Durango, I would build it on the STLA Frame architecture like the Wagoneer. Make it a more budget-friendly alternative to the Wagoneer. But it doesn't offer nearly the luxury features as the Wagoneer; that way, if someone wants that, they can jump to a Wagoneer or Grand Wagoneer. Hurricane SO standard power, HO on upper-level models. A stripped-down SXT model would lack a third row and no panoramic sunroof; a standard one would be just fine. Dodge is about budget-based performance. If you build an SRT model, maybe some luxury touches, but it doesn't need premium touches.
A new STLA large crossover, with three-row capability, would also be added to Dodge. A sporty, but functional crossover, which would be a direct replacement to the volume seller Journey and leave off from the Durango that we know now. Hurricane4 and Hurricane6 power with edgy looks, 20-inch wheels standard, 22-inch wheels on more sporty models. Again nothing overboard with tech and luxury features, to rise up prices.
PHEV models would be great across the lineup, offering 25 to 35 miles of electric range for most everyday travels.
Instead of the Giulia, a two-door muscle coupe smaller than the Charger, to compete with the Mustang would also be on the list. 2.0-liter turbo power would be standard powertrain. Offer the car in both a coupe and convertible, but again focus on no premium luxury features. Make the car about performance. Luxury is a second though. Soft top only, no need for a hardtop converible.
