No, and it will never happen.
I can't remember which site it was on now, but someone on one of them tried looking into a TS3 equivalent and quickly discovered that in order to make it work, they would have to dive into the xml code and change literally hundreds of variables to make them all sync up with the new timescale. Add to this that any mod that affects motive decay or that carries out other time-sensitive adjustments would be immediately obsolete as a result. Throw in EA's propensity of issuing broken patches every other week and it's a recipe for disaster.
I'll see if I can find a link to the original discussion.
EDIT: Here's the link:
