Can I put a YZ400F motor in my 250F frame?

But, it may more more sense for me to put my WR250F motor in her bike and use the 400 in mine.
Will the 400 motor fit the WR250F frame?

It is an Aprilia RS50. 2-stroke 50cc, makes about 6 hp stock. We added a 75cc top end and a ton of other performance goodies, it is fun, but still not fast enough. She is a short woman and we can't find anything else that will fit her. She must have the bodywork and sexy race appeal. The YZ400F motor will absolutely rock in this bike if it doesn't twist the frame into a ball first.
