Zinc gives hardness to copper. So a high proportion of zinc gives a harder brass. If it's harder, then are less flexible.
The brasses what i have used are high zinc contents, so there are quite breakable. Generally, high zinc proportions are used today because are more easy to give form (with rollers, extruded, etc...)
If roman ones are made of an similar proportions alloy, what's the problem? All the troubles that have the roman will be made in yours, so it's interesting in order to do some experimental archeology.
What colour are that alloy? Yellowish?
