Can Doom Bots be a part of the Rotating Game mode?

Hey Everyone! How're you??

Doombots was an experiment by Riot which took your favorite AI champions and twisted them into these super charged beings of terror... and FUN. Doombots challenged your prowess and reflexes in the efforts to obtaining your goal: defeat the Nexus!

My questions are: Where is the Doombots game mode and will it return once more? And could it possibly be added to the rotating game mode? Would this ever be a consideration for this year and perhaps brought again for an Harrowing event? **Also- could more bots be added to the roster??

All the best, and please let me know if Riot did acknowledge this and maybe I just didn't see...

Thank you guys!
