If changed to HC, then the 47K will work just fine.

Should all the LS chips be replaced with HC? And, if so, can the originally specified 47K resistor values be maintained?

Sure; a 74HC10 would work as well as the 74C10. I was just thinking of a vintage chip that would have been Elf-period correct, without having to rewire it for a 4023.
