Simple way to keep all the new Ascendency classes in the core game

My idea is keeping all new alt Ascendancy, of course just after some rebalance in the core game by: 1) we can only swap to alt Ascendancy. Like Juggernaut only to Ancestral Commander. 2) You can swap only in the specific lab by using specific offering ( like gift).
For my perspective it's only win, you already have everything you need to make it real ( just a few days of work), and in the same time Poe will have so much more possibilities with minimum of new complexity.
As a Poe player since 2014 and a person who created thousands my own builds I just can't bear that whole new Ascendancy classes will be gone after 2 months.
What your thoughts?

Honestly, I'm going to miss the new ascendancies, especially for the Scion. Miles ahead of what the live game has to offer and really showcasing how the class is a jack of all trades.

They really need to consider a revamp across the board. The old system is stale now and there are a ton of good ideas with the new ones.

Make them matter once again and make characters feel powerful.

I love old Ascendency, but for now they're all need a bit of love. That would be great if they can change at least a few old Ascendency in the 3.26. Hopefully that will bring new meta

Fully agree with the previous posters:

I really enjoy the new Ascendancies and was even able to semi closely build my favorite build im doing each league with some tweaks, which feel fresh and make me think about my build again.

I personally really enjoy straightforward builds (not synergy within synergy, within synergy). And i have a specific skill gem i really enjoy playing, so having to think how to make it work out within the given constraints is really fun.

I lost some survivability, but gained a lot of damage.

so i really would love to have some shakeup with the ascendancies.
I posted the idea in a different post already, but maybe having some rotating ascendancies per league or so, would enable the game designers to test ideas and then over time polish out many more fun ideas.
