My personal opinion is that I wouldn't consider both Marian and Imperial units together. The topic about removing Imperial units is one, but thinking also of Marian units is another one and IMHO they shouldn't be removed (more easily and quickly to get than Imperial units, and they also cover a larger timeframe).
If slots are needed I would consider only the Imperial units to be cut out, and even after them I would consider rare minor units of any faction rather than Marian ones.
