No. Those are two separate units. You could try a slide-in range with controls on the front and no back panel.

You would need to install a cabinet to contain the wall oven and redo the countertop to support the separate cooktop. Because you now have a gas range, you probably do not have 240 volt outlets required to power an electric cooktop and wall oven. As sushipup1 recommended, purchase a slide-in gas range (example). For an induction or dual-fuel slide-in range, add a required 240 volt circuit first.

Regardless of the type of range, make sure that the gas pipe and electrical outlet(s) are in the correct locations on the back wall to allow the range to be slid back into the opening.
