Well, since I posted this, I have tried it in a teamgame, and together with my pocket (who had a normal cs army), my 50 roman sword champs decimated two opposing cs armies while fighting under 2 forts and a cc. I am also not sure why you think spartiates would be so much stronger than roman or iberian swordsman, why persian or selecid champ cav would be so much stronger than gaulish or roman champ cav and why you disregard the champ pikeman, which are still the most "tanky" unit? Probably every champ wins against 3 citizen soldiers of his type at once (although I have yet to test this).

It might be possible, but it is not really optimal. I'm not sure which champions or CS are we talking about? If it's Persian and Seleucid spear cavalry, yeah. 40 Spartiates will also decimate pretty much anything. Anything else will hardly beat a full, balanced CS army. Please, hold that thought. While watching the Age of Empires 2 DE casts, I've noticed an absurd situation of people having 100 or more Villagers and almost no army. Like literally 5 Scouts and a few Pikes or Archers. The games were either decided in the Feudal age Scout Cavalry rush or they turned into a turtle boomfest that we here all know and love. Which often ends in the trebuchet or bombard cannon wars.  So, for all intents and purposes, we should do our own thing. At least it leaves a bloody mess once two huge armies collide. Also, let's not introduce some new thing that will need to be balanced for years. We have experience with rushed changes, already. 

Maybe we just need to lower the initial rating from 1200 to something like 800.  Many new players aren't 1200, they are much weaker.
