Im refacing the kitchen with shaker white cabinets and thinking of replacing my current kitchen breakfast table area with another 6 ft island, I already have a 4 ft island, and am not sure if another island will make it too crowded. The space is a good size but isnt super big. The room is about 20 ft long by 15 ft wide. Are there any major cons to the second island idea? I will then be keeping the existing island the brown colour it is and the new island will most likely get a wood counter and white shaker cabinets. If the double island is too big, then I will be replacing the current island regardless as it doesnt suit my needs, but I really want to try and use it in this space if I can. Thanks!

I have attached some images of the space:
