Suggestion for Mordekaisers interaction with the Elder Dragon

As most of you know, Mordekaiser just gains the default Dragon's ghost whenever he enslaves a Dragons soul. This does not change with the elemental Dragons. Whenever he enslaves the Elder Dragons soul, he gets a bigger version of the default Dragon.

Now I know this is a lot easier said than done, but is there any chance he'll get the Elder Dragons model when enslaving an Elder Dragon? Considering the fact that it would propably require some work from different teams, it's pretty obvious this won't happen in patch 6.9. But could it be added in a later patch? That would honestly be really awesome!

Also, a gameplay related question, could Mordekaisers Dragon live after Mordekaiser dies, and attack whatever is in his range (kinda like annie's Tibbres change on PBE)? It might be too strong, but if it could be added, that would just be awesome! Seeing Morde's dragon die with him is kind of a sad sight considering everyone wants as much play time with it as possible ;P
