The violins are not omnidirectional point sources. They have complex, frequency-dependent energy radation. A regular impulse response isnt going to cut it. There are ways to capture non-point-source IRs, but none are the same as playing the instrument in the space. Additionally, and perhaps more open to argument, the movement of the performer is part of the sound of an instrument. If the violin is locked in place, with a fixed IR applied, that's not really "what a strad sounds like" when its played for real. I would suggest that having many more microphones would be a nice idea though.
