Why?
RAF Mosquitos and Luftwaffe Me-110s got by just fine without a huge radome on their night fighter variants.
From the NFXVII the Mosquito was eqipped with the universal nose which would allow the fitment of the MkIX (British) or MkX (American SCR720) radars. The SCR720 was fitted to P-61s.
The F7F night fighter used a smaller, presumably less capable, radar.
The F7F was also later in timing than the P-61.
Would have been interesting to compare the later turbocharged P-61C using the P-61E/F-15 cockpit canopy with the F7F.
