I think this looks like a great floor plan for what you are trying to do. Can an island be made in a kitchen 12x14. I can depending on your cabinet layout. Another solution is to incorporate a galley style from a peninsula configuration. Play with your cabinet layout. Base cabinets are 24" deep and a good walkway/clearance is 4'. You may want to consider a portable island that tucks under the countertop and can be pulled out and moved for additional prep space. The space is tight and you'll want good access to the traffic pattern from the hall, through the kitchen and into the dining area. Look at photos on houzz for U shaped small kitchens, and also portable islands. This will give you some great examples. Good luck.
