C4D : Topology - Extrusion - Tips

Dear community,

Context :
I'm currently creating a cyberpunk gun for a video game.
My workflow involves box modeling and edge flow.

I've made the gun using 5 low-poly base meshes. I'll apply subdivision surfaces later for a smoother look. Afterward, I will combine these 5 meshes into 3 texture atlases to optimize draw calls in-game.

Question :
I was working on the tank part, which has a curved top. I want to apply some extrusions to create metal bands that will support the tank. I used the split tool as a starting point for these bands, but once I applied extrusions, here's what happened when the topology had a diagonal shape :

Is this fixable?

Thank you for your help and support,
