Route 128 already shares with 95 from Peabody to Canton, and Route 1 joins in from Dedham through I-93.  So the highways themselves have mixed designations.  But the signs are on separate signposts, and at most of the interchanges the 128 signs are woefully inadequate.  But they could amend the regulation or create an exemption, and if they came to their senses on this issue, they would.
