With the engine out of the car, this mod is cake. I too did it the hard way and did it with the engine still in the car, and it took quite a while as I had to fabricate a tool to ge the bearings out. Mitsubishi had a special tool for this but had discontinued it and was in teh process of replacing it with another one. Don't know if that tool ever came out.
There are 2 schools of thought. One says balance shafts eliminate the harmonics endemic to all inline 4 cylinder engines. The other believes the fewer the parts, the less chance there is for something to break. There is also horsepower to be found by removing the balance shafts.
Just started breaking in the engine that I built with the removed rear balence shaft and the turned down front shaft. So far I cannot feel any vibration, but I have not beat it yet.

Holy overpriced parts, Batman!!!!!
In answer to your question about running a shaft like this, just the same issues as running a stubby shaft.
