Here's the Axis Model One, comes in graphite or silver.

It is one of the cleanest 5 stars I've come across. Note the step-lip, and most importantly, how the spoke interacts with the rim of the lip in a non-intrusive way while also being lighter both physically, and visually. This image explains that

Maintains a bit of concavity even in a 8.5" wide, but gets more aggressive with the 9.5 and 10.5 offerings. There's also a strong possibility that a 20x9.5 +45 will fit all the way around. Would be worth a test-fit IMO.
Alternatively,
The Giovanna Mecca RL

And Dramadio RL

Which both come in some different color combos, I just picked one and threw it up here. Those Giovanna RL wheels are very light, and RL means reverse lip, so the inner lip behind the spokes are purposely smooth and deep, adding to the look of the wheels. Come square or staggered, your call.
