To swap out those massive radiators you need to add considerable baseboard. Can be done, but probably higher cost. You can measure the radiators and there is a web site that does the conversion to how much baseboard you need for equal heat. While costly, you may get better heat distribution. You also have wall space issues in some cases so do a layout first to see what problems you may encounter.

Gas boilers are generally less maintenance cost than oil but propane adds to the cost tool Check prices locally to figure which is best for you.
