I do not recommend putting a wall oven under the counter. Wall ovens are designed to be installed higher. If you install it under the counter, you will find that the oven is lower to the floor than the oven in a range.
Either stick with the MW/Wall Oven combo you show or get a range.
Keep in mind that unless you move from rangetop to oven every day for every meal, it won't be that big a deal to walk a few extra feet occasionally.
Have you already signed off on the "final" design? If so, have the cabinets been ordered?
If the answer is "no" to both questions, you might consider seeing if the layout can be re-worked, but given the locations of the window and door, there probably isn't a different layout that will help all that much if you stick with the MW/oven combo.
