Speed up rerun banners

[fallow sphinx]

With the introduction of ethereal cores this half anniversary, these pulls will expire in 78 days as of writing this post.

This suggestion aims to speed up the re-run banners so that players can pull for their desired units with ethereal cores before they expire.

There are currently 29 limited units

Aqeuor: Tulu/Murphy/Miryam/Corpo/Vortice/Gmurphy

Chaos: Lily/24/Kath/Ryker/Tawil/Mouchette/Ham/Gdoll

Caro: Thais/Sorel/Salvador/Gelot/Doresain/Pickman/Xu/Saya

Ultra: Daff/Wanda/Horla/Clem/Castor/Pollux/Arachne

Can the devs please consider

• Having 4 rerun banners; chaos/aqueor/caro/ultra, with 3 units rerunning in each of these realms

• This way 12 units can rerun simultaneously at one time, for 1 month.

With this system, it’s relatively easy to rerun all 29 limited units before the next patch within 78 days.

Im also open to any suggestions / methods as long as it speeds up the reruns

That might be a good idea in other games, but I think it might become detrimental to most players.
Imagine that you're building your teams for D-tide.
As it is right now, you can farm normal silver between banners to secure some f2p pulls for units you want (assuming two characters you want aren't rerunning at the same time).
If you have four limited banners constantly rotating characters, it's almost sure that you will find three, four, or even more character you want at the same time. That would discourage f2p players who might see this kind of gacha as fomo-inducing and benefit whales, but even whales might be turned off if your proposed change is implemented poorly.

It would be far more beneficial to do one of two things:
First, change ethereal cores. I get why they were implemented and that they were already changed to a degree. I would propose further changing the sources of these cores to monthly quests or rerun-themed ones. Something like having two supports in the rerun banner and a quest to generate aliemus or skey or using posse and exalt a certain number of times (huge or in steps to divide the rewards over time).
Second, change the way rerun banners work to make them into realm-specific Moonless Guide (the beginner selection banner). By this I mean that every month, players would be able to choose up to two realms and three specific characters belonging to said realms. Like so, people can get their desired characters faster while not screwing up the monetization too much.

I should add that I agree that reruns should somehow be sped up since we'll get to the point where characters might only run once a year or during anniversaries.

OR, now that I think of it, we could have a banner with one limited character from each realm and a weekly/bi-weekly rotation. Like so, we can limit the chances of multiple (an excessive number of) desirable characters appearing at once.
Like so, in particular if matched with more sources of ethereal cores, you speed up the reappearance of characters, allow players to gather resources for their pulls, avoid particular FOMO since it won't take a year for the characters to return, and maintain a similar enough format that it shouldn't disrupt the monetize system too much.

valid points, my main concern is that with the current speed of rerun banners, we’ll likely get 2 or 3 more triple banners before the ethereal cores expire, including the one coming on 15th june, that’s 9~12 unit reruns.

players who save their ethereal cores would be lucky to see their desired units rerun and i want to avoid a situation where they are forced to pull or have their pulls get convert to standard cores
