Anyone want to see a BTB/Invasion combo playlist?

Goal: To create a playlist that takes full advantage of the Loadout system, Invasion, and the DLC maps.
Big Team Invasion
Big Team Invasion Slayer
Big Team Invasion 2 Flag
Big Team Invasion 1 Flag
Big Team Invasion CTF Slayer
Big Team Invasion Assault
Big Team Invasion Territories
Spartan/Elite only versions of CTF, Assault, Slayer and Territories.
All DLC Required.
All maps from Invasion and BTB, minus the Invasion Skirmish maps and the Community BTB maps.
No Invasion Slayer on Hemorrhage

Now, a few things would have to be altered in order for this to work out.
First off, Invasion maps would have to be altered to support a fourth fireteam per… team.
Second, in order for “Invasion” variants of current gametypes to work, they need to have Tier/Phase progression. For the slayer based gametypes it’s as simple as progressing as the kill count rises…but in CTF, Assault and Territories…something else has to be done.
Preferably, the Phase should progress as the score rises (I.E. CTF to 5, changes to phase 2 after one team earns 2 points, phase 3 after one team earns 4 points)…however, in lieu of being able to progress from Phase to Phase, an alternative solution is to simply offer the Phase 3 Loadouts right off the bat.

Suggestions? Thoughts? Alterations?
