There's no way to tell from those close-ups...you'd need a room layout showing current piping and what you want to accomplish. Normally, there's a way to do this without jumping through hoops. But, keep in mind you need any relocated pipes to be able to slope down at 1/4" per foot, and depending on how things are currently run, that may be hard to achieve without tearing out more than you may want.
Working with CI can be dangerous...the stuff s very heavy. When cutting out a section, make sure it is well supported, or it could fall and injure you or something.
