Agree, but we need something to make it more versatile
I disagree; prior to its buff BLUDTUPOWA was one of the game's most flexible glyphs. It didn't work for everyone (what does?) but it was performing well in a variety of roles for vastly different character builds. Unfortunately, it was working too well for a few narrow applications, namely piety farming with Binlor/Mystera and burning-spam. This is why it was nerfed.
the old BLUDTUPOWA and I feel you need to justify a radical redesign of the glyph. The problem was that it was overnerfed because of a few narrow cases. Pre-nerf BLUDTUPOWA was less of a balance issue than either the crystal ball or alchemist's scroll, and I'd rather just revert the nerf and leave it as it was rather than pursue any of the suggestions that have been made thus far.
Also, having it use bloodpools will make taking a sanguine boon less of a massive bonus in the end game, and make playing dracul less straightforward.
Dracul's chance of spawning: 1/3
B2P's chance of spawning: 1/3
Chance of both spawning in the same game: 1/9
This situation would only come up in rare situations. Balancing a boon based on a tactical dissonance with a glyph (or vice-versa) makes little sense, since specific combos are actually quite rare. The only deities I think you could justify having a dissonance with B2P are Mystera and Binlor, but unfortunately as piety farms it's entirely possible that the player has no intention of buying their boons (particularly true in the case of Binlor, where it's stone heart or nothing at all for a dedicated caster).
