Hi,
There’s no need to apologize, and one should not limit to just one company anyway. While I never tried Custom/Pegasus hybrid, I did try both in the same guitar and I generally liked both, Custom is still my most favorite Duncan pickup, so I can imagine hybrid - it would sound good. In many ways, it should sound very much like a Norton, so if you have a chance to try a guitar with one, do it. Norton itself is similar wind to Duncan Custom but has a A5 magnet and a brass bottom plate, both of which warm it and darken it up, and it has a similar Eq stock to a Pegasus albeit with a lesser power and slightly less of presence. From what I could imagine your hybrid to sound, Norton would be close.
Cheers
