On the one hand, this type of content doesn't currently exist on SLR, and it would be fun to create, but there are certain technical and non-technical challenges.
CG content needs to be visually appealing. Hyper-realism would require a significant investment to achieve the necessary level of realism, or you could go for stylization. However, since this is adult content, even a stylized approach would require careful attention to details like breast setup and so on to ensure that everything looks good and natural.
Rendering in 8K will take a lot of time, especially with cool modern lighting techniques and post-effects. However, this can generally be solved with a render farm.
The character models themselves aren't a big issue, but rigging and animation present bigger challenges. It might be useful to explore whether there are specialized rigs for adult content. Maybe someone has this information. It possible to use rigs like Meta Human or Character Creator, which come with many pre-made animations, but they are designed for games, not adult content. Also there is an option to implement a motion capture process—there are affordable solutions for this—which would allow us to create mocap from real-life models for CG scenes. However, this would essentially double the workload, as we would need to both shoot the model for motion capture and create the CG video based on those movements.
SLR has examples of using various characters, but most of them are old and involve real-life shoots rather than CG. I think it's possible to avoid IP infringement by slightly altering the characters and labeling the content as fan-made. For example, if we were to create a character inspired by Some Character, we could create a similar costume, behavior and voice, but make enough changes to avoid legal issues. This process would need further investigation.
