I don't think we need to bring Cooperstown into it. Despite the similarity in their names, Scott's career wasn't even long enough to qualify getting on the ballot. He was a below-league average hitter with an absolute cannon for an arm - he easily threw harder than every pitcher in MLB. I'd put money on it. But despite that, he was not really a good defensive player. At least, unlike Boggs, he willingly moved to 1b for the 1992 season. It negated his best talent (throwing), but he probably just wanted to get on the field.
Free agency was unkind to Cooper, who managed to turn his glorious All Star seasons into contracts with the Seibu Lions and a minor league deal with the Texas Rangers. After the latter, he retired at age 29.
Cooper's career lasted about 5 seasons with an OPS+ of 91. Finding a player with multiple All Star appearances with a lesser career would be really difficult...
