The idea? Call them reinforcements and they would be similar to a loyalist mercenary unit, but since Clan's would never hire mercenaries as this would be very dishonorable to their way of warfare and life. This could solve the lore issue though of these units as most did come in as reinforcements and/or looking for a place in the Inner Sphere. They could act as the Clan's "merc " units and almost a loyalist like approach for the "merc" system and there will be more for the Inner Sphere here I promise.
They could add 4 Clans 3 of these would be the reinforcements, one would have to replace an existing Clan that would need to be bumped off the official map post 3060. This bumped faction though would be moved to the Clan "mercs"

The Replacement....It is a bit of a conundrum for PGI once we get to 3060 for the Clans as the Smoke Jaguars are annihilated for the most part and driven from the Inner Sphere by the reformed Star league assisted by teh Nova Cats they chase them to the Clan Home Space and wipe out the Smoke Jaguars for the most part. However with how this game runs, taking out a faction completely would be rather frustrating for those players of that faction by choice. There is nothing saying that some of the Smoke Jaguar Space could be flipped over to the New Nova Cat's, keeping with in lore that they had space on the edge of Kurita space and still in proximity to the Clans. This would not align them strictly with the Inner Sphere only they could attack who they wanted to (Just as any faction can now), this would follow lore IF they players chose to pursuit this route instead of full alliance to the other clans. The Smoke Jaguar's would then go on to be a more "merc" like unit for all the Clans.
(Inner Sphere Circa 3063 concept)



The New Kids on the Block: There are many clans as most know but for the sake of keeping things some what simple there would be only a need to add in 3 more now after the Nova Cat's, I just with my opinion choose the 3 more popular among players and lore nuts (this might be up for debate) I chose Clans Diamond Shark, Hells Horses, and Steel Vipers for the new factions. We can not have all the clans though as this would spread the population out way to thinly! As stated above these would be more like Clan "mercs" with a more approach to encourage some loyalist like ideals to people who just like to fight around, and maybe more pay outs for some cases for each of these or better deal once in awhile on certain Chassis. They would act as mercs do now some what but with out having to attach to a faction contract with having to be their tags and fighting pretty much as that faction (Like MS as Smoke jag or 228 as Stiener ect ect.) Now these merc units would actually have their own flag and faction to fight under while for other Clan's.
Now what this could do is open the door then for 4 new IS factions as well with a similar approach of loyalist Merc units.




The Famous Ones: I would say that for IS to get some of the free floating merc personal to stop jumping around as much as they do that they could offer IS loyalist merc units like that of the Clan Reinforcements. These could include such units as the Grey Death Legion, Wolfs Dragoons, Kell Hounds, and Northwind Highlanders. These I feel are the most recognizable Merc units in the lore, the only one that would feel rather kinda out of place is Wolf Dragoons with some what Clan ties but that is up for debate.
What do you guys think? More factions? More faction skins and mugs! While keeping the population not to divided as my fear for adding in new factions with actually territory. This is not a perfect system and does require some more critical thinking on it (I don't have much time trying to push this post out the door before work.) This i feel also would help with the map and lore issues we would face more so in 3060+ time frame.
Feel free to add to this or thoughts?
