Two? How about several dozen?

I don't find the headstock logo objectionable, its fine with me. A single O would work. Then, if you had a baritone, you could call it the Big-O.
What I really dislike about their headstock logo is that they feel the need to combine their name with the word "ukuleles". Not only is this self-evident, but also a questionable plural.
Their pineapple logo would be way too bulky on a headstock, for my taste.
So for me, best would be either their headstock logo without the word "Ukuleles" or even better, just a stylized letter "O", like they have on a few models like the BK-70R.
I am with SailingUke, I noticed it the first time when browsing Ukes on Mim’s site. I would like to see the stylized “O” on all of the Ohana headstocks. Simple yet classy.
