Reinertsen in "Product Flow" brings a economic framework to product management discussions. If you can incorporate your ideas around roadmap into a formal economic framework, it would be an original contribution.
Most other frameworks are qualitative and seems like they were coined by someone who just graduated from b-school - high on feel good power words but low on objectivity ;)
Reinersten has some videos on youtube which are good intro into his thinking -
