There are extenders which allow you to go further back for speedplay pedals and I'm sure I found some for Look pedals but I can't for the life of me recall where.
That said, I find that with a normally sized shoe (so not a lot of room in front) I am really comfortable somewhere, well, pretty rearward but within the adjustment range. The idea is for the pedal spindle to be roughly in the middle of the MTP joints for all around riding, maybe a touch to the rear.
