@faflec, Joker of Knowledge, I summon you.
I remember that we asked Jiraiya whether he could make Naruto a temporary summoner of the toads so they could reverse summon him from wherever Akatsuki held him, but I don't remember why that didn't happen.
Was that because transferring summonership is frowned upon or was it merely because Naruto was a jinchuuriki and therefore banned from being a summoner to begin with?
If it's just the latter then that could be our last resort method of getting Kagome to inspect the dragon seal personally, at the cost of Hazou or Noburi (temporarily?) transferring their summoning scroll to him.
Having Hazou reproduce the seal as a 3D print, something he is uniquely positioned to do due to his bloodline imprinting it perfectly, would obviously be easier and preferrable. But hey, it could be an option worth keeping in mind.
