Any chance at all for a private league template that include ALL of those mechanics?

People have already played with idols, alternate ascendancies, settlers(multiple times) and necro settlers. Private leagues are mostly ssf and since this will (hopefully) be the last running events before 3.26, wouldn't it make sense to create one giant templates featuring all the listed mechanics?

Could the game handle running: Idols, alternate ascendancies, necro settler, shifting stones, atlas invasion, beyond, sentinels, kalandra and affliction at the same time?

I couldn't bring myself to play phrecia because idols and alternate ascendancies are just not exciting enough, so I have limited experience with both.
Looking further at all the content, I very limited experience with shifting stones, atlas invasion, sentinels, affliction, kalandra and phrecia.
Having to choose between this odd set of 1 or 2 content deters me from even touching the private leagues.

I can see some letter conflicts between shifting stones and idols and between affliction and alternate ascendancies, but other than that, most of these can be paired up to 3 or 4 content without losing playability or causing conflicts.
