Possibly.
However, Dirk showed some 3D model ideas of possible Clubman variations and those were based on the first generation cars. Now, going on to the 'masculine' feel of the Clubman which he mentioned a few times during his presentation, I do feel that the R56's bulkier appearance contributes to that idea. The first generation MINI was, in my opinion, much more feminine and baby-faced, and this would have deviated from the 'masculine' design values. I know Dirk referred to MINI design incorporating masculine, feminine and baby lines but I do feel that the looks of the first generation were biased toward the feminine and baby sides.
