Like the post says, we should have playable homeworld clans. Since there is a big giant space of planets begging to be used, it should be made available. While I don't have any problems with the "Big Four" Clans, I'll admit it is boring to have those clans available to play as. If the only price to pay is that the HW Clans would be fighting each other, I would be fine with it. Maybe the Homeworld factions can have their own events or game modes that would operate differently like 10 v 10. This would even give a clear distinction for the "Invading Clans" and personally, I think it would be nice to see some new faction icons along with some individual colored planets.
Homeworld and Invasion Differences:
Invading Clans
Clan vs Clan or Inner Sphere
Homeworld Clans
Clan vs Clan Only
