Yes, the freezing will move water around causing some of it to end up on the surface of the buds as frost, and that is why I suggest the aggressive early drying once they are thawed. However, I do not see much chance of this ruining anything, it will just mean adjusting the approach to drying. For perspective here, some growers actually wash their buds before drying them, and swear by the technique. If you can dry them effectively after soaking them in water, there should not be any issue with the relatively minor surface wetness after freezing.
Just my two cents of course, good luck with your decision.
