If the pedals are rusted on, you probably won't be able to remove them! The threads are large enough to give you a very strong bond.
If the pedals do come off, then the threads will be fine. This is the most likely scenario.
So get out that long wrench and give it a try.
A bigger problem are those gorillas who overtighten pedals. I once bought a bike where the pedals did not come off, come Liquid Wrench or Cheater Bars. It finally came down to sacrificing one or the other. The pedals were cheap, so I cut off the axles with a bandsaw, then machined off the stubs until the threads released. The threads in the crank were fine, by the way.
