Yes absolutely, but you can just make the range wide enough to wash out the difference (like -2000 to 2000, summing to zero) Then you would probably get more i

Then you would probably get more information from looking at the person thank you could from hearing a weight number that could be +/-2000 pounds

If all but one party reveal their pads, they can trivially determine the other's weight so it fails. Believe it to be secure if only 1 party is malicious, though. Cases for other numbers of bad actors are more complicated...)
