If you mean, will you get parts of wings blown off, see-through damage and the like, the answer is NO.
What we will get is more detailed damage models, but the visuals for WW1 planes are unique to the WW1 planes. That will not be transfered to WW2.
To answer the second part, any plane that would theoretically have this added (theoretically) would by nature require new default graphics for all parts. There is an added element of bitmapping require to "alpha out" the damaged areas. Skin editing on WW1 planes is more intricate than on WW2 planes.
