That sounds like it will work. By the way, these hoppers and all the Weaver cars as far as I know were built to NMRA recommended practice, so any brand of trucks also built to those standards would work. the most common is Athearn trucks which are similar to the Weaver delrin trucks. But Intermountain, Red Caboose, and other typical 2 rail O Scale trucks would set the car at the right height. You might need to do some work on the truck bolster for using other than Weaver or Athearn.
When these models first came out, there were no Weaver trucks, they were designed to use Athearn trucks.
