I'm once again fantasising about a re-launched Horus Heresy range with a core of plastic kits & pondering what tanks that might include made me remember the stormcloud attack boxes so here’s a hypothetical "Battle of Tallarn" Iron Hands v Iron Warriors plastic boxed-set
Battle of Tallarn:

The basic idea would be to have a custom ruleset similar to the stormcloud attack stuff/ Betrayal at Calth & Burning of Prospero ruleset that'd allow you to have some interesting games with just the included minis, but for the Age of Darkness system, both a Proteus Land Raider & Lascannon Sicaran are rougly 200 points, and a Sabre with 4 missiles plus the autocannon is roughly 90 as is a heavy bolter/ autocannon Predator so you've got a relatively balanced force (at least for points). In terms of the factions, the Iron Hands and the Iron Warriors are the big two tank Legions so I thought it's be appropriate to have them facing off and Tallarn is the perfect setting.
Looking at the actual minis, I think these four are all relatively feasible in plastic given what we've seen from how well the Titanicus kits are broken down/ packed onto the sprue, and having cupola crew members in a different pattern of power armour for each different tank would be neat (MkIV for the Sicaran, MkIII for the Proteus & MkII for the Predator, maybe no crewmember for the Sabre?) plus it'd allow for the pintle weapons to be spread around the 4 kits a bit while enabling overall variety. For variants, I'd hope the Land Raider could be built in a way that included options for both the basic Proteus and the Armoured Proteus, and I've looked at the Sicaran turrets and I think both the base Sicaran and the Arcus share a similar enough design that allowing for both from the same kit should be feasible (along with both sets of sponsons). For the Predator, I imagine in addition to the three sponson types, the turret autocannon & plasma executioner would probably fit, although the remaining 3 turret weapons would probably be dictated by sprue space (plus the sponson lascannons could probably double as the destructor for 40k) - the Sabre's options really depend on how small the sprue would be, if you wanted it on a smaller frame it's possible the 4 missiles, autocannon & heavy bolter would be the only available build.
Anyway, these were just the 4 tank kits I thought might feasibly be moved over to plastic were a core-plastic Heresy re-launch ever to happen, and they can actually build a nice little Armoured Breakthrough Allied detachment if you use the Sicaran as the Master of Armour so not a bad grab for Legion players.
