Re: P90's for Wildkat
just google dog-ear P90, lots out there, mostly vintage wind tho- which I'm not sure would help all that much. Loller does offer a hotter wind, as does Kent Armstrong.
They should fit- only one or two aftermarket makers offer chrome covers though, if you wanted to keep that look. 
I have a wildkat- it is a bit dark-, but, I lowered the neck polepieces, and raised the bridge polepieces, plus, I have a "presence" tone setting on the ME-50, I use that and it cleans up real well.
