Actualy no, as I am not sure of the process that is to be used
My only concern comes with the fact that you'd hate to use already dried fruit, then coat them, and finaly another dehydration. It's in that final step that I'm not sure of. The required time would probably not be as long as the time required to dehydrate the fruit themselves.
Although, sweet fruits and yogurt, one cannot go wrong
I'll look deeper into that lovely grub issue

Looked into yogurt dehydration :
The result of dehydrated yogurt is a taffy-like substance. It can either be made into pure yogurt leathers (which needs to be cut in strips of approx 1 inch in width then re-dried for short period to seal the ends before storage) or it can be used in mixed fruit-yogurt leathers.
