I may be late and possibly do not understand exactly the issue, but something
triggered the following thoughts:
You have Grids
some of those Grid objects are Biilboards.
Can Grid objects switch from being Grid to Billboards and back or is Billboard
a special type of Grid and a created Billboard object will always be a
Billboard?
Doesn't this sound like inheritance?
Why not just model entity Billboard ISA Grid? No need for any fancy D2W
juggling then!
As I said, just some random thoughts
Have fun (and a good weekend)
