Silo Special Silent Circuit Alternatves

Thinking of abandoning the silent circuit on my HSS Silo Special and either putting two silent single coils in there or getting a new HH faceplate and putting another humbucker in the neck.

It’s important that I eliminate the hum.

Got two Lollar Blackfaces and a Tyler Special in the bridge.

Anybody got suggestions on what would pair well with the Secret (if you’re familiar with it)? Looking at Zexcoils as singles at the moment. Not sure about another humbucker. I got the Secret because it works so well with singles
