My suggestion here is that you have a tier system with faction choice. When you initially choose a faction as a new player you start off as Tier 1 Loyalty and have a set of unlockables with LP. Easy enough. You can switch around as you want and if you unlock max Tier 1 unlockables with all the factions you can do your Wolf's Dragoon thing like they are talking about. What I would like is a further Tier that is permanent. So if you want to move to Tier 2 Loyalty its a permanent decision.
This cements faction rivalries even more, allows for a more significant decision (I love big decisions), but still allows new players the oops I didn't want to choose that faction choice and play with their friends without cementing their choice initially. This could also create even more variety with only players locked into a certain faction having specific LP unlockables that could include mech specialization bonuses (certain factions prefer certain weaponry and mechs etc) Doesn't force you to play said weapons or mechs but could very softly encourage players to follow lore.
