You shouldn't have to greatly tweak stats if you're already maintaining a habitat that closely simulates what they'd be living in if they were in some African termite mound. If the enclosure is conducive to healthy behavior and intact sheds then it's likely going to be conducive to brooding as well.
Egg rolling isn't an automatic death sentence, either. I know others here on the board have experimented with this to see what effect it had on the eggs to turn them at various points during incubation. The result was that every egg hatched. No problems. I had an egg that rolled out multiple times last year because it just wasn't adhering to the rest of the eggs in the pile and it still hatched without issue.
Not trying to tear down your comment here but if it can spare others the anxiety of finding a roll out and fearing the worst, it's important info to share. I know I was pulling my hair out when I found my roll out the first time and trying to figure out which end was "up". In the end, it really didn't matter. Eggs are incredibly resilient and they are capable of "self-correction" in the event of being rolled or turned during incubation. It's forceful trauma like falling that can mean sudden death for eggs.
