Ideally yes (long term mutual interest), in reality corporate management for AAA gaming is shortsighted.
CoH2 game director openly admits that money talks louder than unhappy fans in post-launch interview (July 2013):
It is not like we have a high opinion on Quinn "every game tells a story" Duffy anyway and like he can teach everyone success story's lesson with DoW3 release. I guess (and hope for him) he changed his mind between 2013 and today.
Now if we talk only about RTS genre, of course the game and monetization model have to be done from scratch because there is no model available on the market today. The only other RTS game retaining a player base is Starcraft2 but wthe platform used for its lobby is probably paid with WOW subscription.
It shouldn't be hard for Sega and Relic to find out that selling cosmetics should be the way to go if they want to make everyone happy. And if they don't, their short coming mind with meet their short coming revenue on the game. RTS genre isn't MOBA with millions of potential players.
