The short answer is no. Mojang changed the way the game runs SSP after 1.2.5. The current method of running an internal sever unifies mods so we no longer need 2 diff versions if we like to play SSP and SMP. Of course I could be wrong, I'm not an expert, but this is my understanding of the game and Mojang's decisions with regard to it's design.
