If there will be both a wall mount oven and a surface unit, I would power them separately. Using a single OCP sounds like a great idea until the family gets invited over for a holiday dinner and supper is cooking on the range at the same time that the cake is baking in the oven.
I would not consider the 2 cooking appliances to be non-coincidental loads.
Even if this works right now for your family situation, what kind of problems are you setting up for whoever eventually buys your house down the road?

Here is an example of 2 appliances...

1. GE cooktop model #JP336DDBB ($649) 7.4KW

2. GE single wall oven model #JT3000DFBB ($1399) 4.2KW

Total KW=11.6

Using 220.55 column B along with Note #3 for 2 appliances we can multiply 11.6kw(7.4+4.2) x 65%= 7.54KW

7.54kw / 240volt= 31.42amps

31.42amps is good on a #8wire with a 40amp breaker.
