I'd pay to see your Brahma raised by a D'Anver hen. Those chicks would be sticking out everywhere, the poor momma.You are such a slave driver! Let those hens go! LOL. Actually, that fighting lasts basically a few hours one afternoon and it's done. They get it all out at one time and the order is settled, or that's how it's always been. But, yeah, they'd outgrow those bantams in no time. Even the Rocks are as large as my D'Anvers within 7-8 weeks so the Brahmas, being so tall, would probably take 5-6.
