Yeah. Hoosiers was a late generation LD, made in 1995 (possibly with the intention that it would be used on DVD when the format was finalized). The Star Wars LD predates that by several years. I don't know how much (if any) the state of the art changed in the interim, but I wouldn't use the later product to set a lower limit for the earlier product.

Also keep in mind the film elements of ANH and ESB were older at the time of telecine than Hoosier's were when it was scanned; with Lucas's admission that some of the ANH film stock was bad, there's more evidence that the SW laserdisc master was poorer than that of Hoosiers'. The greater image area of the latter may also serve to mask artifacts; any small error in the neg/print, transfer, or encoding will be proportionately larger on a 2.35:1 film than a 1.85:1 film (since we're holding horizontal resolution constant).

I'm just not confident that Hoosiers is the best predictor for the quality of the SW DVDs. If I'm only allowed one data point to predict a trend, I'd prefer it to be as close to SW as possible -- same aspect ratio, same photographic stock and techniques, same age when the transfer was made, same postprocessing, etc.
