I had 3, maybe 4 bridge holy divers in les pauls and it's definitely not a pushy pickup, and doesn't have a really strong magnet compared to some other pickups I had at time, and it sounds best as close as possible to strings and boosted by an overdrive in front of the amp
in my experience, alnico 8 makes it hotter and tighter, but too compressed and definitely not better sounding for my tastes
have you tried the true grit? it is not as spongy, but thicker on the low end and more balanced
