It might be kind of fun but could also end up being frustrating. The fit system is entirely different and it takes some time to get used to a TT bike. It took me several weeks to build up the muscles on the back of my neck to be comfortable on my TT bike for any length of time. Turn your head up about 45 degrees towards the sky in your road bike position and hold it there for awhile and you will get an idea if what I mean.
