Mmmm, interesting. I do think the 6 arm ring is a big part of the look of the TA cranksets though.
I found this https://cyclesgrandbois.com/SHOP/TA_Ring_NW.html but that one website is the only record I can really find for it.
It might be a bit much effort for what amounts to an aesthetic upgrade but probably a functional side/downgrade.
Edit: a non n/w ring and a chainkeeper would likely yield the same result for much less effort and expenditure.
NW for TA 5-pin is not a thing that exists as far as I'm aware...BUT I do have a 110BCD spider that fits the TA/SunXCD cranks which I have used for 1x setups with normal rings.
There's plenty of nice cranksets for 110bcd rings though, the reason I use, and love, the TA setups is the freedom and ease of using unusual chainring pairings. And I'm got a big old stack of TA rings accumulated over the years.
