No, as far as I understand, labels/aliases/mnemonics *must not* have
a history, exactly as a SVN revision number does not have a history.
The question "What was r54236 like at r77654?" makes no sense, exactly
as "What was Build_2004-05_custom_special like at r77654?" makes no
sense if "Build_2004-05_custom_special" is the alias for r54236.

I have the impression that you got a different idea of the aliases.
AFAIU, the aliases should be aliases for the revision numbers and
fully equivalent to them.
(There could be a list of "alias <=> revnum" on the server (which
might be transferred to a client as well), the svn tools could look
up the revnum from the alias and then continue using the revnum.)
Please correct me if I got the wrong idea about it.

Could you describe how? I thought it's not possible.

This looks like an Absolutely Great Idea(tm) to me!! I'm not sure if it
