The conjunctions you mention, of Haman's lots vs. the Urim ve-Tummim, is highlighted very well, I think, in the Midrash that suggests that Ahasuerus has all the temple implements, that they are the utensils at his party and which is depected in the recent comic book adaptation of the Megillah illustrated by Jordan Gorfinkel, where he puts the urim ve-tummim on Ahasuerus at the party: https://jewishreviewofbooks.com/wp-content/uploads/2023/03/Esther-interior-1.jpg
Indeed that's why "ve'keilim mi'keilim shonim" is sung with Eicha trope, to remind the listener of the rabbinic interpretation that the vessels at the party were the vessels from the temple. (Not to be confused with the vessel with the pestle: https://www.youtube.com/watch?v=TJ9f2rnjB84.)
Though now I regret not suggesting that Haman might have used the urim and thummim to cast the lot to determine the date of the genocide. Might be a bit too Indiana Jones, but I still wish I'd thought of it before publishing.
