[Standards] Transmit of contact photo per Jabber ID

Good day! I want to create a weather bot which is not a component. However, I would not be able to make a dynamic use of contact photo, as I would with a component. Because, it is not possible to selectively transmit contact photo. I think, that this would have useful uses to different use-cases, so it would be good to create an XEP to it. Please advise, Schimon
