No there is no possibility of overcoming blurring when you rotate a rectangular grid at an angle to a different rectangular grid (except, of course, in the special case of quarter turns on square grids).
There may possibly be algorithms that blur *less* than whichever algorithm is used above, but blur cannot be eliminated.
