They are AVRI pups by the looks of it, still, no complaints on them usually.
Btw, a standard CIJ Jag pickguard will fit your HH, i did it myself. I bet you could pick one up for $10 second hand. Sorry to say this but i think its gonna look a bit of a mess otherwise and trying to put them under the humbucker metal covers is just asking for feedback problems.
Also, standard Jag pups just screw into the body and rely on foam underneath them for height adjustment. So you'll need to pick some mounting screws up and some kind of foam (i used rubber knee pad material).
