As a cunning plan to get the locals into Epic, I've been planning on starting a Horus Heresy era campaign. Epic is better suited to it than regular 40K for a number of reasons - it accommodates scale better, it's at least moderately cheaper, and decent painting can be as simple as a night with a spray gun and a detail brush.
But one of the problems is that the marines of the Heresy weren't quite the same as normal marines. And thus I present the following:
A tentative list:
Legion Line Company - 3308 Tactical Bases. Upgrades as follows: Land Raiders, Rhinos, Vindicator, Drop Pods, Dreadnought, Devastators, Assault Marines, Commander, Melee Combatants.
Legion Armoured Company - Cost of Vehicles4-8 Vehicles. May be either Land Raiders or Predators, at 100 points and 75 points each respectively. Upgrades as follows: Vindicators, Commander.
Legion Bike Company - 3308 Bike Bases. Upgrades as follows: Commander, Jetbikes, Grav-Attack.
* * *
Legion Terminator Detachment - 3504 Terminator Bases. Upgrades as follows: Commander, Dreadnought, Drop Pods, Land Raiders, Vindicator.
Legion Tactical Detachment - 300Six Tactical Bases with Rhinos. Upgrades as follows: Commander, Dreadnought, Vindicator, Drop Pods, Land Raiders, Melee Combatants.
Legion Assault Detachment - 1754 Assault Bases. Upgrades as follows: Commander, Vindicator, Grav-Attack.
Legion Devastator Detachment - 2504 Devastator Bases with Rhinos. Upgrades as follows: Commander, Drop Pods, Land Raiders.
Legion Jetbike Detachment4 Jetbike Bases. Upgrades as follows: Commander, Grav-Attack, Landspeeder.
Legion Bike Detachment - 2005 Bike Bases. Upgrades as follows: Commander, Grav-Attack.

For each Legion Company, you must take one other Detachment. You may not have more than twice as many Detachments as you do companies.Note: Upon the occasion of the Heresy, the inspirational prescence of the Warmaster and the blessings of the Chaos Gods make the Chaos Space Marines just as fearless as any Loyalist. All Space Marine Legions use the "And They Shall Know No Fear" rules. Note: The Melee Specialists upgrade replaces one unit's bolters with bolt pistols and close combat weapons, thus improving their CC to 3+ and reducing their FF to 5+. It costs -5 points. It can be taken once for each unit in the formation. * * *
The points costs of just about everything that originated in the Black Legion list have been increased to account (more or less) for ATSKNF. Decimator got +50 points because you'd figure a War Engine'd benefit even more than average. Infantry got +50%.
The hope is that the company mechanic will encourage a bit more of the "big sweeping formation" style which seems appropriate to the scale of heresy-era battles. It also will hopefully guide people toward armies that are vaguely appropriate (there will also likely be a "50% of all this army's companies must be X mechanic so as to prevent the mighty White Scars Armored Legion).
Grav Attack Statistics are to be determined later, and cost to be determined from that.
I'm a little worried Melee Specialists is overpriced. OTOH, it's rather necessary to include it - otherwise the BA and WE are high and dry, plus most Heresy assault troops didn't have jetpacks.
Is there anywhere I should look on the site for particular guidance or inspiration?
Thoughts, criticism or unqualified praise? Am I missing anything? Do I have anything grossly unsuitable or grossly under/overcosted? Am I mad?
