Smallest dia spinner for Sensenich prop?

Looking for the smallest diameter spinner for a Sensenich 3-blade ground adjustable prop - pusher config, 912ULS, Calidus.

Anyone know if the 210mm (8.3") dia DUC spinner and bulkhead will fit? It would be the perfect diameter and aspect but the offset outer ring has me wondering if it would fit. The larger 9.5" Sensenich spinner would be too big for the cowl opening.

Alternative suggestions would be helpful.

Thanks!
