well, COGAS.... gas turbines for cruising, and steam for sprint. I would use it the other way around, as steam can be relatively efficient, and gas turbines are light and powerful but thirsty. you can use it, but the funnels do not really match now
also, you seem to have copied the parts from another ship... as said before, be certain you know what all parts do before you use them
but, try out, make mistakes, and maybe you arrive somewhere where I would not expect it to end..... but which might work!
