We don't have any plans to tamper with the art of existing tier sets. Transmogrification is being implemented, in part, to allow nostalgic players the option of wearing old gear without having to worry about the stats anymore. But, we don't want to go back and actually alter those looks. That'd almost defeat the purpose, especially given we'd prefer to focus our time on designing new sets to allow for more customization options (including aesthetic, stat-less sets to be used solely for Transmogrification).
The art and animation teams are incredibly busy, and sometimes I feel they don't get enough credit for the amount of work they do, or how much work is involved in each project. There are a number of projects on their list -- many of which players would love to see progress on -- but this isn't currently one of them that I'm aware of.
