Instead of an extra alias, why not export $VISUAL or $EDITOR, and rely
on sudoedit(8)?

It's not a "limitation".  It's a feature.  ;-)  Re-read the sudo

I'd be surprised if most of your aliases would ever require root
privileges, and are anything but one-off shortcuts for your personal

For those that do, I'd suggest replacing them with a function (or
script) that tests for root privileges (using something like id(1)), and
invokes sudo when appropriate.  

Otherwise, you may want to consider using 'su -m'.  That will your
current environment unmodified and all your existing aliases will remain
available for use.
