Yeah, the laminate is like an eighth inch thick. According to Warmoth, it will not affect your tone, or at least it wont affect it enough to be noticeable.
Maple with a Rosewood fretboard is the standard Fender neck equation, so obviously the two woods should work well together. I cant image that a Rosewood laminate on a Maple body would be much different than a Rosewood fretboard on a Maple neck.
