Cooktop Hole Too Big

Planning to replace our aging gas cooktop but the existing hole is 950mm wide.

There are only a handful of models on the market that will fit.

One option might be to fill the gap on either (or one) side with some sort of infill, as this would then give many more options in terms of cooktops that will fit...ie pretty much any "900mm" model on the market.

This might actually be useful as it would give a place to put hot things on. Current benchtops are laminate and don't really want to replace them at this stage.

If I went for a stainless fill-in bit on the side how would that actually work? Would it just sit on top of the existing bench? I thought if that were the case the 'surface' that the benchtop sits on would then be uneven...but if the stainless was thin enough, would that matter?

Or would you router the surface so the stainless sits flush (or below) the existing benchtop.

Another option would be to get a frame to go right around the hole (rather like a picture frame)...presume this would be easier to install.

Who would I get to make this sort of thing?
