Not in the general case, no.
} When globbing generates a line that is "too long" (configurable
} by the user), the command is automatically replaced by one using
} xargs or zargs.
There's no hook that's available after globbing has occurred but
before the command execution is attempted. There's also no hook
that's available "between" commands in a pipeline, or in a compound
command line using semicolons, or in a structured loop body. So
the closest you can come is, in an interactive shell, to override
the ZLE accept-line function, parse $BUFFER yourself, perform the
expansions, test the lengths, and reassign a rewritten BUFFER before
the line is really accepted.
This is almost certainly a lot more work than the result is worth,
and there's absolutely nothing you can do in a non-interactive
situation such as a script.
