Automotive WI: suppose Henry Kaiser had listened to Joseph Frazer?

In 1949, the demand for K-F products slowed as the Big Three as well as the established independents rolled out fresh postwar offerings. Joseph Frazer, a veteran of automobile manufacturing, advised slowing down and simultaneously developing a V-8 engine. Kaiser heeded none of this advice. It took several years for K-F to sell the glut of cars built, and there was a falling out that led to Frazer leaving the company and the Frazer nameplate disappearing altogether.

Suppose Henry Kaiser hadn't said (as he supposedly did) that he never retrenched, and instead took Frazer's advice? Could:
  • Frazer have survived as a marque past 1951?
  • K-F continued in the US after the 1955 model year?
  • A combination of K-F and Willys (similar to OTL) have been successful enough to bring in other independents (Hudson; Nash; Studebaker; Packard) and perhaps made the Big Three into the Big Four?
 
1947 model year cars sold very well, mostly because the military work Graham-Paige at Dearborn factory didn't interfere with the car line(G-P stopped selling cars in 1940) and were able to start producing new cars ahead of the rest of the industry.
The cars were not so great, but they were available to be driven off the dealer's lot when all the rest of the Big Three could only take orders.

The downfall of K-F was baked in almost from the start, like selling that factory and moving into Ford's huge Willow Run plant that had been making B-24s. They would never need all that floorspace, and the most productive thing they did with it was to sell it GM 8 years later, after they bought/merged with Willys-Overland for their factory in Toledo

Joseph Frazer dreamed too big, and missed the little things, like not having a higher HP engine, even though G-P had good supercharged Six, and a Straight Eight that had 135HP in 1935, and was reliable.

They were charging Cadillac prices for Buick quality Plymouth styling and Chevy performance.

Now things would have been better to have something like the Henry J sooner, and without the costs of running Willow Run, might have had enough to restart their own engine line to be ready for the upcoming Horsepower Wars, with Chrysler coming out with their Hemi in 1950 and Old with the OHV 'Rocket' in 1949, and merge with Willys-Overland asap.
