Offspring dough ball and final pizza...moist and airy rim crust

I do use a bowl residue compensation when making large batches of dough for pizzas and usually have a little leftover dough from all of my batches.  I decided yesterday to use two leftover pieces of dough from my boardwalk pizzas of two batches and also used the leftover piece of dough from my Detroit pizza.  I first balled the two leftover boardwalk pieces into one dough ball and then took the Detroit leftover piece of dough and wrapped it around the boardwalk style dough ball and then pinched it shut.

I wondered what would happen when making this offspring pizza today.  The dough ball did not feel too sticky when it was cold, but when it warmed up it did feel sticky.  The offspring dough ball was just stored in a plastic bag since yesterday.  I floured the dough ball and opened it.  The offspring dough ball did open nicely and there was no sticking problems on the wooden peel.  I now wonder if the offspring dough ball did co-mingle together or stayed separate.   

What surprised me the most is that the offspring pizza had a nice rim rise and also was very moist in the rim.
