The American version of the Hispano had a jamming problem when mounted in a wing, so it's no wonder it was rare. It's also a good reason for perking the F4U-1C, even if its performance doesn't quite justify it.
You don't perk it because the guns jammed, you perk it because the alternative is a sky full of F4U-1Cs spraying and praying.
Not much need for a night fighter when you don't have night to fight in; that wasn't exactly the main event during the war anyway. It's only recently all-weather (night is a weather) has become the standard. Even the F-16 wasn't originally designed for night work.
Now, if you want to provide local dot-dar to radar aircraft (even when out of ground radar coverage or when the local radar is disabled) that might prove entertaining.
