Of course there is.

If solar sail probes can change their orbits over time (which they can), then they already have enough thrust. There's no static friction to overcome, so there isn't a minimum thrust that you need to reach.

As long as you can continue to apply thrust over time, then you have a solution. It doesn't matter if it takes 6 hours, 6 weeks or 6 months. Even a single probe moving the right piece of debris prevents tens of thousands of more pieces being generated. Imagine what three of them could do, or twenty...
