The Magic of Shazam!
I have recently learned that the classic DC villain Vandal Savage, a foe of heroes across the generations from the original Justice Society of America in the 1940s to an upcoming series of appearances in The Flash, was co-created by Alfred Bester, author of my favorite book of all time, The Stars My Destination. I had a germ of an idea about how to work Vandal Savage into The Magic of Shazam!, tying him into Shazam's early career as Champion (magic word: Vlarem) and possibly teaming him up with King Kull, but nothing definite. I still don't know how exactly, but now that I know he's a Bester creation I must work Savage into MoS! Vandal Savage is a 52,000-year-old immortal Cro-Magnon; so, compared to him even the approximately 8,000-year-old Wizard is a spring chicken.

I don't know if I'd use it or even for what I'd use it, but I came up with an alternative way of forming the Wizard's name, Shazam. The real S.H.A.Z.A.M.:

S = Wisdom of Solomon
H = Strength of Hercules
A = Stamina of Atlas
Z = Power of Zeus
A = Courage of Achilles
M = Speed of Mercury

Now, Black Adam's magic word "Shazam" is formed using the names of several Egyptian deities and in the Golden Age Mary Marvel's "Shazam" was formed using Greco-Roman goddesses; what I've come up with here is just an alternative Greco-Roman "Shazam," maybe for a still very vague and undefined villain Major Marvel:

S = Stamina of Sisyphus
H = Courage of Hector
A = Strength of Ajax
Z = Speed of Zephyr
A = Wisdom of Aesop
M = Power of Mars

I'm also thinking about reviving the villain Mr. Who, the principle difficulty being I know virtually nothing about the original character. The only idea I have about him is that his codename is a horrible pun on his name like Mr. Freeze (Victor Fries): Mr. Who (Mr. Hu). We all have good ideas and bad ideas; take a wild guess into which catagory the above falls. Then again, puns have been a part of comics for a very long time.

I'm also working on a couple more brand-new villains, King Celsius (all I have is a name and I desire to make him different than the other DC "ice" villains*) and Vainglorious (I have a costume and part of a motivation, I'm still playing with the name and the origin/motivation). Other possible names for Vainglorious include Excelsior, Exemplar, and The Perfect.

Lastly, I think I've nailed down the first year of The Magic of Shazam!:
No. 1 "Giant Atomic Robots, Part 1"
No. 2 "Giant Atomic Robots, Part 2"
No. 3 "Giant Atomic Robots, Part 3"
No. 4 "Giant Atomic Robots, Part 4"
No. 5 "Giant Atomic Robots, part 5"
No. 6 "Giant Atomic Robots, Part 6"
No. 7 "Faerie Tale, Part 1"
No. 8 "Faerie Tale, Part 2"
No. 9 "The Mechanical Man of Mystery"
No. 10 The Crocodile Mob in... "A Piece of the Action"
No. 11 "Kristallnacht, Part 1"
No. 12 "Kristallnacht, Part 2"

*Ice-themed villains I can think of off the top of my head (if there are others, they must be pretty obscure):

Mr. Freeze (foe of Batman)
Captain Cold (The Flash)
Killer Frost (Firestorm)
The Icicle (the JSA)
