It should be fine. Your going to get a little shrinkage, but MBS is fairly stable. With the solids.. like the cabinet door frames you might get some checking. Those can easily be filled with a a wood fill stick in seconds though. I'm partial to the
Mohawk brand. A single stick will last you for years.
At least in AZ it's nice and dry so expansion/contraction will be fairly minimal after the first year or so.
