I would be considering the impact of such a complex object on overall file size and manageability.
Also depends on whether you need to have it show in 3d window only or on sections/elevations.
If only in 3d window, I would look at creating a surface for this item with photo as texture (use photo format with alpha channel where the 'voids' can be transparent) and scaled to required size. Then, place a suitable element (wall, beam etc.) with created surface on appropriate face(s).
Then, in section/elevation, place photo as a figure where required and scale to suit.
Otherwise, create one module of lacework with slab, copy as required, convert to morphs, combine and 3d rotate to suit. However, would try and reduce complexity as much as possible for required use.
