Why don't you try to give us weights of your gear or at least makers and models from which we can make some suggestions on what to replace first or leave at home.
Alcohol stove, cheap replacement and big weight savings I'll bet over what you had been using, if, only heating water. Many alky stove systems now are only designed for specific sizes or even brands of pots if not up on that trend. Many items have multiple uses also.
