This is so funny. I used to own a similar kitchen in the same city, built in about the same year (1991). I could make no one understand how frustrating the kitchen was because it was a huge room with a tiny area for the cabinets and counters.

There were 8 sets of doors and doorways in the room - the five you mention plus a pantry, large double folding doors for the laundry area, and a powder room.

After 13 years in the house, I finally had had enough and started to work with a kitchen designer. When my then husband learned what the cost was going to be, he said we may as well sell the house. So we did.

If you are not prepared to sink some money into making the kitchen more functional, you are going to be very frustrated every time you try to prepare a meal, bake, etc.

I suggest you cross post this to the Kit forum. If you know the room dimensions they could come up with something. In the mean time it looks functional.

Instead of removing walls, you could consider closing off doors to gain more wall space. Change the sliding glass doors to a single regular door. Close off the door to the den, if there is another entryway (or if you can create one). That might give you more room.

Sometimes walls can be removed and a support beam put in to support the upper floor.

Without knowing the size of your family or your cooking/dining needs, I do have to add that one of the most functional kitchens I've had was also the smallest I've ever seen, in a tiny studio apartment in Boston. If the layout of the kitchen is well-planned, you might not need as much room as you think.
