Trying to emulate a 'tone' is pretty much a 'chase the rainbow' exercise in my book (if trying to be VERY anal about it). That said, trying to get close to 'tonal range' well much depends on amps as well as pups and these things are less critical.
I hav'nt owned a Marshall for a looooooooooooong time so cannot comment in conjunction with your amp. However imo I can get tonally close with my Custom Warpigs.
The invader (bridge pup in his V copy) is a ceramic magnet and therefore a more 'modern' pup anyway.
I am yet to purchase a Nailbomb so dunno, may be ok.
As for Painkiller, IMO, not so much,hard to explain why,just sounds too 'British' for want of better explanation. Maybe a Cold Sweat.
Difficult as my ears are mine and yours are yours.
ALOT depends on amp/settings but if I were looking the Painkiller would not probably be my first choice.
