So gravity bends space, and black holes bend space in a loop. Is it possible for there to be a gravitational field somewhere in space, just strong enough, that it bends the light emitted by our system back to us so we could see ourselves?

A black hole bends light at all angles including 180 degrees, so yes it will send a bit of your light back to you. Said light would be so munged up it would be difficult to extract an image from it though.

There could be a series of less severe gravitational lenses that gradually send an image back to Earth. You might even be able to rig it so that the distortion wasn't extreme.

If you do the math, you will see that bending light in this fashion is highly unrealistic.

What would the math be?

Very few photons would be bent precisely 180 degrees in passing a black hole, as noted by ImaLooser. The resulting image would be incredibly faint.
