Too much effort and money, probably, especially since they have a good spot in the market right now.

However, Jefferson's Ocean [1] whiskey is an experiment where Jefferson's took 68 bourbons aged 6-8 years, blended them together, threw the barrels onto a ship, and sent it on a 6 month sea voyage. Apparently, it yielded some interesting, tasty bourbon. I haven't had it, I havent even seen it in person. But be on the look out, i guess.
