2 stroke fuel in a 4 stroke engine

Hi,
Quick and very common question: Can you use 2 stroke fuel in 4 stroke engines?
For now the only nitro plane that I have has an OS FL70 in it which loves the S&W 15% 4 stroke fuel with a castor/synthetic blend (unknown oil content). I am soon going to get a new airplane, but there is no way that I'm going to buy a 4 stroke that costs more than the airplane this time around, so I'm going with a 2 stroke (likely an OS 46AX). Once this happens, I really want to try to stick with only 1 fuel for both of my nitro planes, and I have no clue how to do that.
Do you think that 15% nitro with 20% castor/synthetic would do well in 2 strokes and 4 strokes?

Thanks
Mike
