If you have a look at the more modern *BSD,
you'll see that vi contains ed
and ex. It should be possible to backport that to V7 and likewise to

*****
Coherent vi is a link to Berkeley screen editor elvis by Kirkendall from
1990.
elvis is a clone of Unix vi and ex editors.
elvis command structure ressembles command structure of line editor ed.
