It is kinda Silver Age-y...although in the Silver Age, Thomas and Jor-El would've had some kind of adventure together instead of just sitting around talking. Missed opportunity, IMHO. Bonus points if they could work Hippolyta in there somehow. ;-)
It also reminds me of Elliot S! Maggin's novel "Last Son of Krypton", where Jor-El makes contact with Albert Einstein, and Einstein is the one who decides that the Kents would make the ideal foster parents, and arranges things so that they'll be in the right place to see Kal-El's rocket arrive.
