I thought the same thing a few months ago... and guess what?
There IS such a thing as a Concert uke-stick with geared tuners, and I HAVE ONE!!!
I emailed Rigk at Risa about it, and they have indeed been fitting on geared tuners (though not pegheads, they're Planetary geared tuners commonly used on Banjos) on their new batch of concerts.
So if you want one, email him in advance to send you a Concert with the new geared tuners when purchasing.
And it works bloody well. I sold my Soprano uke stick in the past because I couldn't get used to the frictions, but the Concert uke-stick with geared tuners works like a dreaM!
Same old Risa uke-stick goodness, but now with geared tuners!!
