Take them down. Replace them with square fluorescent tube boxes. Because they are square you can adjust them one way or another to make them even, spread them further apart or even off set them depending on where you need light. They will cover up the holes and nicely light the area. I have two in my kitchen. Hope you can see this from the pictures.
WOW! that sure is dated and no solution at all...glad it works for you but....fluorescents are terrible task lighting.
You can correct the misalignment and add a small ceiling medallion to cover an mars in the ceiling. Paint them the same color as the fixtures and no one will ever know. You can also make your own out of wood if you can't find a premade the size you need.
don't do fluorescents
I used a decorative plant hanger hook screwed into the ceiling to 'swag' my light to where I wanted it. My light fixture had a long enough chain and cord to do that. If yours doesn't you will have to add more chain and electric cord.
The person didn’t say they had to keep the lights. My kitchen has garden doors across the end wall and a mirror on the other end so there is lots of light. I also have other lighting but not shown. The square lights can be adjusted to cover the uneven holes.
