Solen,
Looks like you've got a nice project on your hands! I love my Shipmate propane stove/oven and wouldn't want anything else, but that being said, if you are intent on going with just a cooktop, then that means you can build a nice storage cabinet below just make sure you can gimble your new top so you can heat things up while underway.
One thing that I would stay away from is a stove/cabin heater combo because of the close proximity of the ice box/refer. Having the regular propane stove right there is bad enough, but I can imagine a heater sitting right there radiating a tremendous amount of BTU's, baking your ice
All that being said......I love the nautical look of this:
