Ashley, don't discount the value of natural light, especially in a space where remaining windows are not large. You can often run a regular height counter top in front of an existing window if you don't have a backsplash on that wall (the window trim would be removed at the bottom and the vertical trim cut to meet the counter top). The window can still function and if the trimwork is handled well, can look just fine. You would have a very shallow window well, which could be filled in with wood to meet the counter height (I have a similar situation in my bathroom).
Consider a pair of under-counter refrigerator and freezer units on that wall, to free up the floor plan and open up the visual space. That is what I did in my 1930's Tudor (we have a regular sized fridge in the basement). Sometimes you have to think far outside of the box to come up with a solution that really works and doesn't compromise the original integrity of the house!
