I would have to concur with that. In that case I'd rather have a single base with multiple models, even if that base is meant to represent more guys than the actual number of models on it.
In that vein, I was seriously at one point (as in, still thinking it'd be neat, but it's way back in the backlog of things I'd want to do) considering making some Thirty Years War armies for Pike & Shotte, using the standard base size but substituting each 28mm figure for four 15mm figures.
