I'm not a material engineer, but I am told that this design is at the limits (with safety margin) of what could be done with TL8 steel at 1 g internal gravity.

A rough and ready way to estimate maximum internal gravity would be to take any substitute material for the hull, find out how many times stronger than steel it's tensile strength is, and you have maximum internal gravity.

A side note, to avoid motion sickness in the general human population the RPM needs to be kept under 2. This may not apply to aliens or gene modded humans, but here's a handy calculator:
