Anita, I think the set you like is beautiful. However, consider this, legs like that table has will not allow for extra chairs. If the same table was a pedestal table you could get 2 chairs down each side. I had a Wicker table with a 48" glass top before this table and I had six chairs. I now have a 46" octagon table with 4 big chairs and two smaller chairs with low backs. Don't let those small chairs deceive you, they are full size chairs the seats are as high as the ladder back chairs, just the back is smaller. I can get chairs 6 around this table and have squeezed 8 around it in a pinch. I think 4 x 3 would work well, but like I suggested watch the table legs, they can hinder the amount of chairs you can use. I also had a bench at one time (inside the bay window) we were a family of 5 when our kids were growing up, so we had 3 chairs and a bench. This nook measures 9 foot 1" wide from the counter (with the bananas on it) to the end of the wall. . .The bay window is 8Ft wide. I took this tonight after I measured... from the center of the bay window to the end of the first glass pane on the french door the measurement is 8 ft. Also notice that the chairs are not huge and they fit under the table well. ( they can go in even further than the photo shows) This allows more walking around room when the table is not in use. I am a very visual person and use a lot of visual aids when doing or building furniture. I suggest you take your current table and add a faux top with wood, or cardboard or anything that would mock up the size table you want in the room, add the chairs and see what it looks like. Also consider a 42" round table (pedestal) with a leaf. It would give you a lot more room for everyday use for 4 people and when the grandparents come put in the leaf. We made this table 48" and when it was all done and we put the chairs around it I saw that if it was a tad smaller the chairs would fit under neath better so we cut it down to 46". Every little bit helps in a small area. Hope this helps. joann

Perhaps, in lieu of pendants, something like this: https://www.homedepot.com/p/Kenroy-Home-Corbis-4-Light-Bronze-Island-Light-93595ORB/300513035?cm_mmc=Shopping%7CG%7CBase%7CD27L%7CMulti%7CNA%7CPLA%7CInteriorLighting%7c71700000038836110%7c58700004241533705%7c92700035280099904&gclid=EAIaIQobChMIy96Bk8Dw3gIVjf_jBx0DyAHHEAQYBCABEgLtmfD_BwE&gclsrc=aw.ds

If all the other doors are 6’8”, no, it won’t look right. Consistency is important. The issue here was the original decision to use 6’8“ doors in the first place. It has locked you into an expensive all or nothing change scenario. You’re also potentially introducing incompatible structural alterations, and exterior cladding changes, with moving the header up. It depends on the load that the wall carries. Get out your plans and have the structural evaluated first. Improper flashing won’t be confined to the doors. Start inspecting all of the penetrations. From the roof through the dryer vent. All require flashing. https://www.buildingscience.com/documents/information-sheets/common-flashing-details

The frame is not installed yet. My understanding is to have allowance of half inch of the door frame. My other concern is given the size 8ft x 8ft, do i need to pay specific attention to the frame to make sure it can hold the door ?
