FWIW, I suspect there's a reason two-spoke steering wheels are rare today: Liability Claims! Mid '50s to '60s, some upscale models had wood covered rims with 2 perforated spokes & were popular- Corvettes for instance. But 'upper-size-percentile" drivers tend to grab the steering wheel in a death grip and use it as a grab-handle to haul themselves in or out of such usually-low-roof cars.
Ferraro and MOMO wheels are -I think- heat treated 2024 aircraft aluminum (non-TIG-weldable- I tried) with wood or plastic rim covers under leather wraps. With only two spokes, the rim flexes quite a bit if used as a grab or assist-handle. Over time, something cracks. Two-spoke and banjo wheels are not illegal in the US, but If you drive 'vigorously', I would not recommend any 2-spoke wheel. Do not even start with Citroen's one spoke steering wheel.....
