Finding Tomb King Treasure for Age of Sigmar.

After finishing up the Warcry Starter set (two warbands and terrain) I decided to delve into my Warhammer box and see what I could pull out as a next project.  This box consists of armies that I purchased over the years from ebay, and bits and pieces that ebay sellers had thrown in with other purchases as I got into painting High Elves and Skaven some years ago.

Lo and behold, from the dusty sands of the back of my closet (actually just...dust) emerged an army that I always thought was really aesthetically pleasing, but which I never got around to painting...

Tomb Kings!

Now that Warhammer Fantasy 8th edition is no longer (officially) with us, what would I have that could be used for Age of Sigmar? (I know that there are warscrolls for TK units, but they aren't going to be updated). Would I have anything that could be used for Legions of Nagash?

With the very kindly help of multiple people on the Warhammer group in Reddit, it appears that yes, I have enough to make a small army that could be fun to play. As I only play friendly games, I could probably also stay on square bases (ducks for cover...)

Here is what it looks like (sorry for the bad pictures). Note that there is plenty of conversion work to be done (and no shields are attached as I will paint these separately for convenience.)

Skeleton Charioteers - use as The Sepulchral Guard

x10 TK Tomb Guard - use as Grave Guard.

(Back) x3 blocks of 10 skeletons - combine into a blob.

x2 blocks of 5 skeleton cavalry - use as Black Knights.

x10 Ghouls and x1 Tomb Banshee.

(L-R) Necromancer, Tomb King (use as Wight King?), Necrotect (use as ???)

Summary:

• X3 blocks of 10 skeletons. (Two of which have musicians and standards).
• X1 unit of 10 Tomb Guard - counts as Grave Guard.
• X2 units of (5) Skeleton cavalry - counts as 10 Black knights.
• X1 unit of Sepulchral Guard - 7 assorted skeletons made from Skeleton charioteers models.
• X1 Tomb King. Could put on a spare skeletal horse and use as a Wight King on Steed OR I have a High Elf Star Dragon I could put him on? (Counts as Lord on Zombie dragon?)
• X1 Necromancer
• X1 Tomb Banshee
• X1 unit of 10 Ghouls.
• x3 TK chariots that could act as grave site markers.

I also have (but can't use for AOS): 
X1 metal screaming skull catapult (metal, unassembled) 

Finally I have an additional X4 skeleton horses x4 skeleton archers and X1 metal skeleton barricade model from an old limited edition release (Harry the Hammer) that I came by. If I can get the bits for another skeleton horse I could probably kitbash the archers into riders and replace their bow arms with spears/ lances.

I'm looking forward to taking these on in a time-saving fashion, so will probably go with spray undercoat and Contrast paints. Already my mind is turning towards seeing how I could get up to 1,500 points relatively easily and add some Oooomph:

-Arkhan the Black?
-Another necromancer and a block of skeletons?

Thanks for looking!
