Congratulations. Your solutions are either (a) move away from how they design foes in 3.x and use the techniques that they introduced in 4e and continued in 5e to get away from 3.x foe design or (b) just reuse something that someone else already put the work in.Bah. Jot down the basics, decide on the major spells (handwave lower-level spells), major items, and so on. Only if the NPC is going to be with the PCs for an extended time, and possibly played do you then go into the minutiae. Otherwise it's just not worth it. Or just steal a NPC from some source and change the name.
Thank you, you provided a great example of how foe design was broken and how it's been fixed. I know you didn't intend to support my point, but you strongly have.
