You're making it much more complicated than it needs to be. First off, tear-off the old roofing materials. Then replace any damaged decking, from the looks of the cabin you can shingle , but I would put down an underlayment called Weather Watch, or Ice and Water Shield. Besure to re-install according to MFG specs. They are printed on the wrapper for a reason.
Save the expense of reframing and install the roofing correctly.
