RS3 already have a lot of duo and trio bosses in ED3, Solak, Raksha, Demon Flash Mobs, Nex etc.
GWD3 probably may have some duo-trio Nex of its own.
There are plenty of duo/trio bosses already.
If you are talking about OSRS, no saying they can't add such duo/trio bosses, but don't expect they will drop anything of decent values that can be sustained. Unless they come up with new boss mechanics that can't be botted, any duo/trio "bosses" will just become trash in a short time.
