Although I can't seem to find anything else that matches your inquiry other than the mod you linked to, I can't imagine that remaking the potion would be more difficult than editing the item in the CS. If you are confident enough in your own CS mastery, I could probably do it for you. What effects would you consider best for dungeon diving?
Weak: Detect Life, Chameleon 25% for 300 seconds
Moderate: Detect Life, Chameleon 35%, Feather 50 for 300 seconds
Strong: Detect Life, Chameleon 50%, Feather 75, Fortify Security 15 for 300 seconds
Grand: Detect Life, Chameleon 75%, Feather 100, Fortify Security 25 for 300 seconds
That sounds like good dungeon-diving help to me! And, if you decide to whip up a mod that does this, thank you.
