I'd let a potential buyer decide if that's a solution or even a problem.

More cabinets isn’t needed. But a better design is. That’s beyond goofy looking. It has no balance or rhyme or reason. That needs to be fixed ASAP.

I agree with Joseph - let the market dictate what FMV is. I don't think making expensive changes to appeal to a potential mythical buyer makes sense.

Personally I don't like anything about that kitchen so adding a few cabinets wouldn't sway me. However, as Flo posted, it might be appealing to someone who is swayed purely by style and thinks it's cool and trendy and for that buyer adding some upper cabinets would have no impact.
