Help Decide: Mortar Or Mini Ground Cover?

Outside my home is this rugged stone patio. There's a significant amount of it but the previous homeowners clearly didn't care that their winterizing routine was breaking up the precious mortar holding all the stones in place. With much of it gone and plants starting to take over, what's a girl to do?

In many places, small ground cover has started to fill in and the look has me itching to continue the trend. The combination of soft leaves and hard stone is a good one, but will it ultimately push the stones further apart and do more damage than good?

Is this one of those of those times that beauty doesn't beat out brains? The real catch is that our patio is 20 feet off street level and as the tiles push apart, I fear they'll eventually slide down the hill and break on the street below.
