Interesting idea. Remove both the turret and the bomb-aimer's position and recontour the nose. Perhaps A Dutch East Indies version using a Bohler 4.7cm M32 anti-tank gun (or even 2 - at a combat weight of just over 600 pounds, the B-10 should have been able to heft two). If using only 1 Bohler, then perhaps supplement with a couple heavy machine guns?
Also, the Dutch had a lot more B-10-equivalents at their disposal than the Chinese.
Anti-tank guns were in short supply during the 1942 campaign, but this is WIF-world, so anything is possible.
