I am wondering if a Painkiller bridge may work here. IIRC it is brighter than the Jugg and certainly has a good amount of power behind it with a hard hitting bottom, so it might saturate equal or more than a Jugg.
For a glassy neck the Impulse HB comes to mind as it is designed with a single coil quality in mind. Look is different though. The bridge Impulse might also be interesting, but I know too little and am not sure about the saturation part, though the brightness should be there. Perhaps a Blackhawk bridge to match tone and look? That would also make a SC choice easy with a cobra.
An impulse set should actually do just what OP is after here based on his description. They're certainly brighter and more saturated than the juggs but won't push the mids as hard in any particular spot, which isn't so bad in basswood.
To add to that, if you ask, the BKP guys can wind an impulse middle SC to go with the humbucker set. The SC was designed to keep up with the bridge humbucker when installed in the neck in a H/S guitar. It's not yet gone full "public" but exists in my guitars as my #1 neck preference, actually developed before the neck humbucker. It's very, very thick, hot and almost sounds like a P90 with it's rolled off highs and lows. Should make for huge tones when blended with a split neck or bridge coil. Because of it's voicing it takes better to 500k pots than most singles I've tried which will make it ideal in this guitar.
For a bridge pickup option, the Ceramic Blackhawk will be a bit closer to the jugg in terms of low-mid voicing, and is definitely a more metal-oriented voicing than the impulse. I wouldn't say the Ceramic Blackhawk is brighter than the Jugg but it has more cut in the top end. Comparing to the C-hawk the Impulse has smoother, thicker highs, like a rebel yell and neutral mids, I daresay tighter lows and it's clearer sounding, overall brighter and it's a little less hot. The two frequencies we cut the most out of when we voiced it, comparing to the C-hawk were the low mids and top end of the treble region. Both the 'hawks and impulses have about the same amount of saturation which is more than the Jugg. Both work great in basswood. With a rosewood fretboard, and if you're playing mostly metal I'd be inclined to recommend the Ceramic Blackhawk for the bridge position for a bit more cut and chug, but if you want something that will be more versatile the impulse wins, especially for mid gain tones, warmer cleans and driving a lot of effects.
The impulse neck certainly could be described as glassy as I tried to retain the elements of the neck SC that I enjoyed, it's an asymmetric wind like the VHII, which also means it's great for splitting if you use the hotter coil. Won't sound harsh. There's a great example of that bright neck characteristic in this video at about 2:06:

The aftermath will probably be too dry for if you want something more saturated than the Juggs, and based on what you've said if you went for a MM bridge you'd probably want to pair it with a trilogy suite in the middle and a Cold Sweat in the neck.
Can't really comment on the HD as I don't have enough experience with it to give proper advice here but a lot of folks love it in basswood.
In summary, I'd recommend an Impulse HSH set or C-hawk B/impulse SC/Impulse N or Miracle man B/Trilogy Suite/Cold Sweat N
