Sounds like you are going to embark on a fun project. In addition to testing out the water soluble stabilizers on both the top and bottom, you will want to use the same color bobbin as the top thread. That way both sides will be the same.
Just try to remember that standard bobbin thread is lighter in weight to the top thread. So, if you have small details or words, you will be working with more thread than you normally would. Be sure to do a couple of test sew outs of those details and adjust the density if and where possible.
