Would it be possible to detect objects that are just outside the Observable Universe by the gravitational influence they would have on objects that are near the edge of the Observable Universe?

Not in the way you are probably asking. Gravity and light travel at the same speed - if something can have a gravitational influence on something we see then we can also see it directly.

Caveat: The earliest light we see was emitted about 380,000 years after the big bang. All the light before was scattered around and didn’t survive. This is different for gravitational waves. It could be possible to see the effect of gravitational waves emitted earlier and therefore at slightly larger distances.
