no space on the other wall, it's the fridge/pantry.

Could you take a picture of it anyway? Without knowing the full picture it's hard to give advice.

Side note: can the oven and fridge not be next to each other?

I like you idea of removing the cook top and putting a range and microwave where the ovens are. I would not want to sit near the cooktop or cook with the big vent overmy head. The center of the U looks cramped too me and I would look into changing or moving the end with the cooktop in it. Maybe an island facinf the other direction.

putting in a stove over there means cutting current cabinetry and damaging tile countertops. That entire tall piece needs to be removed. you might damage the finish on the pieces next to it. Can you refinish those?

you plan on getting new counters?

the two biggest things I see that need to disappear is that huge vent hood and your florescent lighting.

what should you do? well, is this your home or a flip? If yours, do you like cooking on range or do you like your wall oven? microwave over a range are horrible at venting (they work, but after years of doing so, it becomes clogged w/oil and grease buildup and just gets yucky. I'm removing mine to the island)

You could get a microwave as built in and keep it on the peninsula. but again, these are all modifications that will cost money.

see in this pic how you can barely see the micro off to the left? (range on the right) yours could look something like this

I see oak cabinets for sale on craigslist ALL the time. entire kitchen cabinets for $500. you could remove all of yours and replace w/one of those, and just paint them. A lot of work, yes, but it wouldn't be expensive

cheapest redo is just look into getting a newer vent that isn't a monstrosity. this may require additional ducting. Then the lights. get rid of those and stick in recessed lighting. You don't want pendants hanging over the stovetop, so forget that part unless you move it.

here's the best I can get if that helps. There is just one a one door pantry to the left of the fridge. No room for a stove.

Here's what I would do - assuming the idea is to keep as much as possible: replace lighting with cans if possible; remove hood over stove and re -vent, possibly adding some pendants, replace the black appliances with white; then if budget allowed, find a fantastic statement countertop.
