I feel like I might be looking more quickly than I should, but I feel like this could work. I also feel like it'd be OK without moving the garage door. The plus of not moving it would be a shorter path from garage to kitchen with groceries....and from kitchen to half bath. :-)

As far as banquette vs freestanding table... Could you do the kitchen and try the table with an inexpensive bench in that location before committing to the banquette?

Thanks rhome410 for your input. Depending on how much my cabinets price out to, I may need to do just that!
I forgot to mention that I would be using the newly acquired counterspace for my coffepot and toaster. The theory being that a second person could come into the kitchen and get breakfast without interfering with my primary work zone which would be the counter to the right of the rangetop. It would also double as a landing zone for the fridge.
If I kept the doorway where it is, do you think it would be too far away to put the coffee/toaster in the closest tall cabinet beside the banquette? I plan on putting my Vitamix left of the sink and my stand mixer to the right of the sink in the corner. I really want to keep my countertops free and clear since I am losing countertop square footage.
If I keep the garage entry door, one option I thought of would be to wrap the uppers and lowers with the countertop around the corner towards the patio door. I currently am planning on a 15" deep pantry but am not opposed to just wrapping the uppers and lowers so I have a bit of extra countertop. I can only go 15" deep, so it may be weird to have 15" deep base and 12" wall cabinets. I guess I could use 9" deep uppers. Would it be weird to have the coffepot/toaster station all the way over there?
The second option I thought of would be to have a range instead of a wall oven, thereby allowing me to keep the existing doorway, and have counter top to the right of the fridge. I would just have to find another space for my pots and pans, which are currently under the rangetop. I really do love having them separate but this is not my dream kitchen, just the one I'll be in for probably the next 10 years, raising my children.
Aargh! So many trade offs, I know. Once I mess with one area, another problem pops up in a different area.

If you are not set on symmetry of each elevation, perhaps the range or cooktop could move slightly toward the right corner to get a bit more counter space and a bit more room for two people to occupy the space between the DW and the cooktop.

I would also consider using a table first and then creating a banquette later on if necessary.

Or have you considered going back to the freestanding table, closer to the door, so those wrap around counters would do more for you/make more sense? The door could move a little right?

Then you could have a nicer sewing space, maybe, where you now have the banquette.

Also forgot to respond to this:

Those are very important years to have things the way you want. And 10 years can become 15 or more in a hurry. I enjoy having the ovens and cooktop separate with the kids in the house, because they can bake while I cook, and vice-versa. I also love having my pots and pans so handy, and not having the hot oven in front of my legs while I cook. Some range doors can get pretty warm, and even if not, there is a vent somewhere, and the heat when the door opens. I wouldn't give up keeping them separate if you can make it work at all.
