The L1200 baseboard is 640mm wide and 690mm deep - Reducing the size would compromise stability. Also, if you reduced the depth, you'd often be overhanging the front edge with the easel. Weight would also be a concern. These things weigh 45Kg, more if it includes a transformer for a colour head.

Certainly grab the L1200 especially if it comes with a good set of accessories (masks & mixing boxes) - It is a solid piece of kit that will last years.
