I honestly think this would benefit Matt more than Jeff. Not that Matt would be a "superstar" but that Matt would get a big payday that he's not making in the indies. They might be utilized in the Tag Team division for a year or two, but after that I think they would just fade away. Everyone always wants to have that "feel good moment" and the Hardys back as a tag team would surely accomplish that, but personally, I would rather their tag run be left where it is now; a great memory. What happens if they do join back and both end up doing something stupid? The tag team that I can brag to my kids about getting to watch in their prime, showing them old DVDs and matches, are now just something that my kids would associate with a negative connotation. I for one hope that never happens because the Hardys, E+C, and Dudleys in their prime was one of my favorite aspects of watching wrestling as a teenager.
Could it happen; of course. I just hope not.
