On “What's an acceptable way of doing an IBL environment maps generation during runtime?”
…e easily discarded. Although, many approaches have a more analytical way of approaching the IBL probes.
Instead of providing the static, pre-computed irradiance, you’d provide parts that allow you to relight dynamically in runtime as well. Think of it as statically baked with a dynamic component.
PRT Probes are a perfect example of this approach.

Other approaches moves away from the cubemap idea and instead precomputes the information on the surface itself, like Light-maps and Surfel Irradiance.
On that note, realtime indirect illumination is a huge topic with many different solutions and we could probably spend the next couple of weeks talking about them here.…
