Are you sure all of those were consolidated into 1 regiment? I know the 25th and 31st were consolidated at one time but I don't think all of those were consolidated into one regiment that early in the war. I know that late in the war they were all consolidated and that Bunn commanded but that was like in 1865. I know that the 25th operated as its own regiment all the way through the battle of Franklin in Nov 64. They were all in the same brigade together and I presume that is what you were meaining. Other regiments in this brigade were the 1st Ark Mtd Rifles and the 2nd Ark Mtd Rifles all commanded by Daniel Reynolds. Perhaps I misunderstood your email but I don't think they were all under Bunn in a consolidated reg't until 65.
