Not quiteSo basically, we're reinventing the P-47
The Wright R-2600 never took to turbo charging very well. granted they only tried a few times.
There was also sort of a hole in GE turbo line up. the B series turbos worked with 800-1400hp engines, later ones do better with late model P-38s. but they operated 3-4,000rpm higher rpm than the early versions.
The C-series started at 1800hp to 2200hp. The early Wright R-2600s made 1500-1600hp. You don't have the required air flow from the B- series turbo. You might be able to restrict the C Series to lower air flow but the C series turbo was about 100lbs heavier than a B series. You are going to need 33% more cooling air for the intercooler for a 1600hp engine than for a 1200hp engine. If you cut the rated altitude down from 25,000ft to 20,000ft you can use a smaller intercooler and less airflow.
Until 1940 comes the .50 machine guns were only good for 600rpm (and in testing often that didn't work) and we have a lot of airplane and powerplant tied up for only four .50 cal guns.
