Switch your Minecraft Nickname between your minecraft accounts

Hello,

I want to make suggestion for Mojang/Microsoft to add some type of easy nickname switch for the new Java Account Migration to Microsoft Account.

Lets say I have 2 Mojang minecraft accounts and I will connect them to Microsoft account.
Then I could easily switch my nicknames from my already own minecraft accounts.

For example:

I connected my two Mojang minecraft accounts "AppleJuice" and "OrangeJuice" to my one Microsoft account.
I want to change my main minecraft playing acc "AppleJuice" to "OrangeJuice" because I like OrangeJuice name more and I dont want to risk getting chance of other people taking my name OrangeJuice.

Why do I want this?

There are many 3rd party sites that track minecraft names and shows when certain name will be avaible again.
I am worried about changing my name to something else and losing it when trying to get it on my main minecraft acc. I have my own main minecraft acc "MrAltik" and want to change it to "Altik" (I own "Altik" also).

Right now I need to change "Altik" name to "Altik123" (for example) so "Altik" name would be avaible to claim after 30 days to my main minecraft acc "MrAltik" . BUT there is big chance of other people seeing my short name "Altik" being avaible to claim and "sniping" it.

Because Mojang want to "migrate/transfer" minecraft accounts to one Microsoft account it would be great to have this option to switch our already owning names to our other minecraft accounts.

I hope I explained it good.
