The difference would be the amount of time for the protein to be digested and reach your muscles. Choosing the later wouldn't make a significant difference but to help avoid any difference. I imagine taking in the solid meal a little bit sooner (pre workout) would help.
If you are going to do this I would recommend that you might want to keep the meals relatively light. Nothing that would obstruct your performance. Although I have not noticed any difference with my performance whether or not I consume a large meal but I have heard that with some people the meals don't sit to well. You could always eat your chicken with a higher GI carb to possibly help speed up absorption.
I don't know just throwing out some ideas many of which I have done. Anyhow when it comes down to it I haven't noticed a difference between eating solid or liquid meals other than the covariance. The main thing is you eating.
