Concrete onto paving slabs for garden building

[wingit]

I'm putting in a concrete base roughly 5.5m x 4m for a garden room, I'm also redoing the patio which has about the same floor area. From the patio the 40mm thick paving stones are to be removed.

The area for the new garden room concrete base has been dug out.

Is it feasible, in the interest of reducing waste and possibly overall cost, to put the patio pavers into the dug out for the new garden room base and pour the new slab onto that?

Thanks

No problem, smash them up when you put them in.
