Do you think 5.X would happen on Earth?

Since from what I could gather

Every Planet/Area that we land, except for maybe Belobog and Penacony, has some connections to the Astral Express members, like with Dan Heng with Luofu, March 7th with Amphoreus and now Himeko with Planarcadia

Do you think that 5.X would be about Welt? Like, out of the current Astral Express, he is the least developed member in the Group, and with the Universe needing as many Powerhouses as it needs right now for the Anti-Destruction Alliance

Wouldn't it make sense for Welt to try to return home? Since after all, There are at least 2 Powerhouses that could definitely helped in the battle against Destruction

That being

Kiana - The Herrscher of Finality - and confirmed Emanator Level Being

And

Nahralab/Nana - A Scion of Permanence - who is also extremely old, far older than even some Aeons, with only Phaenon being the only older than her, to characters that have confirmed ages at least

With this two, they would definitely be great additions to the Alliance

Especially for Welt, since Kiana could upgrade and make him be stronger and be more ready for combat and not entirely rely on the Cane of Eden all the time
