Morphology
The meaning 'very enthusiastic or keen about a proposal' is directly derivable from combining 'hot' (high excitement/fervor) with the prepositional relation 'on' (about/regarding) and 'idea' (a proposal). This follows a common adjective + preposition + noun pattern and is cross-linguistically familiar, so a B1 learner who knows the constituent meanings should be able to infer the MWE.
Etymology
Hot on the idea paints a simple picture: if you are hot about something it feels warm and urgent, and being 'on the idea' shows you are focused on that plan. So hot on the idea means 'very enthusiastic' and ready to support or act on it.
