I doubt it would solve your problem.

Imagine a macro file is only present in one of the directories. You'd
end up with the risk of mixing macros from both directories.

To work around this issue, you'd have to switch "ACLOCAL_PATH" depending
on which directory you'd want to use.

As a work-around to this problem, I once had been using wrapper scripts
to aclocal, located in corresponding */bin directories and to switch

[Meanwhile I found it easier and less error-prone to install appropriate
autotool-toolchains several times using different prefixes.]
