I would think this is possible. I've often agreed with the other party's lawyer that oral arguments on MtDs are unnecessary and then we just let the judge rule "on the papers" without anyone having to be there in person. The judge can then just file a written order with his ruling. Bear in mind that motions and discovery are highly frowned upon in Small Claims courts that I've litigated in. And 95% of the time the court will rule in favor of the bigger party if they bring a lawyer, just out of general hatred of courts for unrepresented litigants.
