Pre-Heresy Thousand Sons Army

What can I say, I've been contemplating on converting and collecting a Pre-Heresy Army ever since I read the first Pre-Heresy novel.  However, I ran into some road blocks with the idea of a Pre-Heresy army.

1) Which army should I create?
2) Do I create a Loyalist army or a traitor legion?
3) If I create a traitor legion, how far along will they be corrupted?
4) Toughest question, which codex will I use? (Chaos, Space Marines, etc)
5) I would love an army that really stands out from the rest.

Several Pre-Heresy novels later, I finally decided on creating a Pre-Heresy Thousand Sons army.  In addition, I'm pretty set on using the new Blood Angels codex for a few reasons.

1) I like their selection of psychic powers.
2) I like the idea of being able to field a Librarian Dreadnought (How cool is that!)
3) Finally, I like the BA units (Sanguinary Priests, Fast Vehicles, and Special Characters)

Next, I needed to find or create an idea that popped out or screamed Pre-Heresy Thousand Sons.  Before long, I ran across a few sites where fellow Hobbyist used Tomb King and other conversion bits from several independent miniature sites.  I mixed these with Chaos Bitz and liked where the look of the army was headed.  I've added a few pictures below.  

Maxmini is one such site in which they sell Pre-Heresy Terminator Shoulder Pads and Marine Helmets

I should warn you, the models in the pictures are not complete.  They all require heads, shoulder pads, back packs, and a few little extra bits. 

Basic Components (the picture is a little out of focus)

Two Librarians (each is sporting a Glaive or Spear)

Sanguinary Priests

Two Sergeants with Power Swords

Two Sergeants with Power Fists

Originally, assault marines.  Now they will be used for tactical

marines and the swords and bolt pistols are just for looks. There

are approximately 14 models armed similar to these four.  I have no

 doubt they'll look sharp mixed in the tactical squads. 

Just a few Tactical Marines with Bolters

Tactical Marines with Meltaguns (Split between four squads)

Tactical Marines with Lascannons (Split between four squads)

Devastator Marines with Missile Launchers

Devastator Marines with Plasma Cannons
