While that's very true, don't let that dissuade you.  Biggest problem is getting the product into DS correctly in the first place, then finding the new asset. So if your familiar with that quagmire, you've most of the battle won.

I've been acquiring "older" assets for some time now, as the artistry is there (some of the best on the planet I think), just a bit hindered by the technology of the time of release. Which is why use DS only as an intermediary & export out of via OBJ, or FBX for characters. My head would 'splode trying to work in DS frankly, but it is doable. I'd suggest tackling each prop separately though, as to not get overwhelmed.

From there, I can apply the texturing in PBR, and they really look great.
