New Champion Trio

Would it be possible to have a group of three champions to be released as a group in a patch(kind of like the Dou release of Xayah and Rakan)? The Reason why I ask of this because I have three champion that I would like to join the League of Legends Champion pool.(If this is an idea that you would want me to share more about, then please let me know.) The idea I have for their ultimate spells. First champion ultimate is to sacrifice themselves to preform area of effect spell. Second champion ultimate is to buff them and an ally, though if the ally they buff is killed then they could revive them but with a cost. Third champion ultimate is multi step spell giving them a chose of using it there first target or second. I have the idea for the spells already but want to know if you are first interested in this idea before going more in depth.
