Yes, for sure get nearfield monitors for the studio environment. But they won't work for a live situation. It is pretty much impossible to find speakers that suit both because the requirements are so different. You pretty much need to decide which is the highest priority studio mixing or live amplification and base the decision on that.

I really can't imagine trying to mix a studio mix with a powered 15" cabinet, but then I also can't imagine trying to use a 10" nearfield monitor for live stage use. It's apples and oranges ....
