In our kitchen remodel, we ended up gaining more ovens. We now have three ovens, and I find I use them quite frequently. In fact, I find that more ovens are a lot more useful than more burners. Knowing what I know now, I'd happily give up all but two of my burners, rather than giving up even one of my ovens. It takes a little while to learn how to efficiently use ovens in cooking. But you then discover how much time and labor they can save.

The other thing that I learned is that small ovens are much more useful than big ovens. They preheat faster and they take up less valuable space. We have a large oven in our 30" Bluestar range (I love the amazing broiler which gets a ton of use in our household!). But the two other ovens are a 24" Miele CSO (must get one! it's awesome!) and a 24" Miele SpeedOven.

I also find that 12" of space next to the range is useless. 20" is still a little tight, but you can adjust to that. 30" would be my preference, if I was in your situation.

And for baking, I love having a big open counter somewhere. We have a wide and extra deep counter for this exact purpose, and it makes a huge difference when rolling out dough. It's also helpful for making pasta dough.

So, this leaves you with a couple of options. Get a range with a couple of smaller built-in ovens. The LaCanche models always felt really attractive to me for this exact reason. Or downsize at least one of the wall ovens. You could also do what we did and get a 30" range, so that you both save space and gain a full-size oven. And then complement with 24" wall oven(s).

Maybe, post a floor plan and ask for more detailed advice on how to lay out your kitchen?
