Mazzle, just a thought/suggestion:
You're aiming for lower memoery usage right? And you're going more and more Ace2, right?
How about using ag_Unitframes instead of discord? They're customizable, not as much as discord though, and they have the possibility to create your own styles. Though I don't know if it's possible to make the bars vertical, but hey, since you seem skilled I think you'll figure it out.
I know you've already got it configured for discord, but I think this would be worth looking at.
Cheers!
