Access stronger troops beyond max lvl through cc donation

Hi all..
I guess it will be quite nice to get extra level of troops (maybe +1 or +2 lvl according to a clan's xp lvl) beyond the current max level troops only from Clan castle troops donation.This might bring us more teamwork and get rid off the useless lvl 1 or lvl 2 cc troops upgrade for max troops donators....
The clan perk bonus should work as it is written...e.g clan lvl 10:donation upgrade-2 levels should just upgrade max troops+2 levels..the stronger level which a player could not get from barracks........this will further increase the value of high level players..thanks all

I had a similar idea posted on reddit about legendary troops. If a max troop was donated to a CC it became legendary. It would receive minor buffs that new troops get, and it would also get a new graphic and be much larger in size. Something about a giant dragon coming out of the CC sounded really fun.
