It is going to be a long time before consistency returns (if ever). There is going to be two different themes for the the narrow bodies across both mainline and Rouge with the likely majority of aircraft without lie flat seating being the "Dream Cabin" and the remainder being "Glowing Hearted". The XLR's and 78X with all be "Glowing Hearted" so you will know what you will get on those aircraft. It seems highly likely that AC is working with Collins and it will be the Aurora for the XLR (since it is herringbone and not reverse herringbone like the Adient seat) and the Elements for the 78X (willing to wager on that). Then the rest of the wide body fleet that AC plans to keep for a longer period of time will slowly get reconfigured with the Elements seat. I would think that the entire 787 fleet get reconfigured, though whether they start with the oldest first is a wildcard. The 788's are the oldest and some are pretty beat up. It seems pretty unlikely that they could get more than 20 J seats between door 1 and 2 (and they have said they only want J between door 1 and 2). They could tighten up the galleys and shift things a bit to get 12 seats in the D and G rows but that probably won't occur. Same could be said for the 789, but I suspect they will stay at 30 J seats. The 77L's aren't likely to get reconfigured based on what Gallardo has said about the aircraft, but I guess that depends on what AC orders to replace them (I am hoping for an early A350 order cuz I think it's a great aircraft to fly on). And clearly the A330's don't get a new cabin as most of them have just been reconfigured. So essentially AC is going to have two themes in their cabin's for a long time. Most passengers likely won't notice as the Super Diamond and Elements seats are pretty similar, but true consistency will likely never occur.
