2 girls from the 90's touted as anal queens Tera Hart and Jordan Lee never did an anal scene that lasted longer than 90 seconds, it would be interesting to see how they would hold up in an anal scene from this decade.
Nici Sterling though I am sure would hold up to today's standard, that is if anything is left of her rectum.
While she only did a few anal scenes it would be fun to watch glamour girl Dyanna Lauren in a modern anal scene.
The most fun to see might be the late great "Big Momma" of porn Trinity Loren. She really hated being in porn and I don't think she had an anal scene that even lasted 60 seconds. I could just see her getting ravaged by about five studs from today in an anal gang bang. Although when they were done with her they might tie her up to a spit, slow roast her, and then eat her, plenty for everyone.
