Should SMTown Give EXO-CBX another comeback before Xiumin's Up and Coming Military Enlistment?

With recent news of Xiumin's military enlistment, I personally think that it would've been appropriate that SMTown gave all EXO-Ls a very nice gift, which is a small comeback for EXO-CBX with a non-album single. Which EXO-CBX could have promoted for 2 to 3 weeks, that could have started either last February or early last month in March. Don't get me wrong, it's nice that SMTown is giving EXO's oldest member, Xiumin, a fanmeeting event, but the fanmeet would have been better complimented with an attached comeback. 

EXO-Ls deserve a gift from SMTown prior to Xiumin's up-and-coming military enlistment, they want to see him perform one last time before he leaves them. Even if it's not with his complete EXO group, however, let it be with his subunit group, EXO-CBX. 

EXO-CBX's supposed comeback could have consisted with the following in my opinion....

One MV Teaser and Trailer

      (Drops about a week apart)

Non-Album associated MV release

      (Drops one week after the trailer)

Radio, Talk and Variety Show Appearances

      (One to two weeks worth of schedules)

One stadium concert show to promote the single

w/ an included final fanmeet with Korean EXO-Ls 

and some International EXO-Ls.        

      (Promotions for the EXO-CBX's Xiumin Farewell Concert 

       could start at the beginning of the subunit's Radio, Talk

       and Variety Show schedules)
