I went with plan B which is much simpler:
Rename the pages directory to something short and on topic (for an extra keyword

) .
Here's how to do it in case anyone else wants to rename their pages directory after it is already installed with content.
First duplicate the pages directory.
Rename the duplicate to new name.
Change the advanced settings pages to the new name.
Now to clean up and send your old page links to the new directory.
Use this in .htaccess and replace newdir with the new pages directory.
RewriteEngine on
RewriteRule ^pages/?(.*) /newdir/$1 [R=301,L]
Delete the old pages directory.
No down time required.
