How big is your living room?

Livingroom is 190"W x 131"L

Where is the water supply? Will there be gas for a stove?

yes, there will be gas for stove. The water supply is on the right of the pantry door, along the 24" wall space. We have an open basement and can move it if necessary

Your space is a wonderful challenge.

I'm wondering if you could demo the pantry entirely and put in a hyper-efficient one-wall kitchen across the exterior wall. (eta: I'd put the trash pull-out to the right of the sink; it's wonderful to wipe the prep counter straight into the trash bin and your primary prep counter would be around 54" wide. If you're doing Ikea Sektion, the 18" wide trash/recycle pull out is my favorite as it holds two large bins perfectly.)

For seating, perhaps a narrow farmhouse table (32 inches wide) with bench seating that tucks completely under to keep the aisles as clear as possible when they're not occupied. Being so close to the sink the table could double as a seated prep space.

For increased storage, your 82 inch window would need to be reduced to around 36" but there's clear space on the porch end of the room for adding a large window or widening the doorway for a patio door.

I've been watching a lot of "Escape to the Country" on You Tube and I've fallen in love with the eat-in kitchens so common in the UK, which kind of inspired this idea...

I'd move the pantry opening towards the chimney as much as possible or totally get rid of the wall b/w the pantry and the kitchen.

Here's what I'm thinking.

Edit: I have trash under the sink.

Those aisles are very narrow, but with such a challenging space maybe
the rules have to be overlooked. The kitchen aisles in my older home
are similar, although the appliances are arranged so that it works
better. I was working on a variation of the above plan, without altering
the pantry (1)--bengiesbride's plan has emboldened me ;), so I'll post it. The work area can be flipped, so that the DW opens into
the long aisle (1a), but in that plan the dishes could not be loaded directly to
the upper cabinet. If the trash and DW are flipped (1b), the DW can be
unloaded to the upper cabinet to the right, and there is a little more
prep space, but the DW is in the prep space. The sink is more centered on the window in that plan.

Plan 2 uses
bengiesbride's suggestion of removing the walk-in pantry, but instead of
the one-wall kitchen, I drew a peninsula with a backsplash to contain
splashes, and the built in seating the OP mentioned. The pantry is
recessed into the long wall, protruding 6" into the kitchen--if it can't
be reframed with a header, you can work around individual studs. I have
a similar pantry in my kitchen, only 6" deep. It's more work initially,
but it holds a lot of canned goods and boxes.

ETA, another 'out of the box' idea. The shallow cabinet could have by-pass doors to hide the folded table, and it would add extra storage for canned goods or hanging utensils a la Julia Child.
