I wouldn't worry too much about 10" wheels with the different sized tires but would be ready for the difference in transient response since the relative sidewall spring rate of the front vs the rear is changed (i.e. fronts in this case have a higher sidewall spring rate relative to the rears versus say using 10" and 11" wheels). The rear could feel a bit sloppy in transient conditions, and it would be easier to use sharp steering inputs to break the rears loose, etc. We're talking very fine points here, but they exist nonetheless. I'm guessing it will work out fine.
