Connecting two of the conductors in parallel would of course reduce the resistance by a factor of 2. As you can see in the wire gauge table, a factor of 2 change in resistance corresponds to an increment of 3 gauge sizes. So you would have the equivalent of 19 gauge.
I can't say, of course, whether or not that would be satisfactory in your system from a subjective standpoint, but from a technical standpoint it strikes me as being marginal at best.
