What Reno Melitensis says about the number of units sounds good to me. Try to imitate the proportion of different units in the legion.

But: there was nothing like a "consular legion" and a "normal legion". If an army was led by a lesser magistrate the legions were normally the same as if led by a consul.

First the "legio" was the entire army of Rome. This coincides with the fact that in this early time there was presumably only one supreme magistrate (praetor). Later, when the two consules were established, the Roman army consisted of two legions (including always the allies), each led by a consul.

Soon the two legions were no longer enough. In the 3rd c. already a normal consular army consisted of two legions (always with the allies, so two legion army = two legiones and two alae). An army led by a praetor, proconsul or propraetor or a dictator could have the same form. Sometimes the consular army consisted also of 4 legions. This was the case for example at Telamon 225 BC, where the Celts were caught between two consular armies.

In the second Punic war a lot more than 6 legions a year were raised. At Cannae both consuls were present and each consul had a 4 legion army, together about 80000 men. But also for example in Spain and Illyria Roman troops were present at this time. In some years of the war 25 legions fought in different places against the Carthaginians, Greeks, Macedonians, Celtic and Iberian people.
