Wiki says: "After the audition, the Corsican Brothers will turn down the player for the role if either
Agility or
Endurance is under 8". The term "is" means, to me, that current value of those stats will be checked at the "after the audition" time.
Another reason to believe the same - is mentions of taking buffout for getting perks in the ultimate F2 guide whenever increased Endurance is required to make such perks available, for example for Toughness perk, quote: "Protection is good (but spending char points on
Endurance is not, so take
Buffout if you want this)". I never seen anywhere any mention that in Fallout 2, "natural" Endurance value is required for something of the sort. Note, i read Luck is that way in some regards, you see, - so having high natural Luck is different in this sense; but none of other SPECIAL stats are so, afaik.
Yet third reason to believe the same - is logic: becoming a porn star is done by doing good enough during shooting a movie, which in the game takes merely few hours; it does not require doing similarly good, endurance-wise, throughout whole life of a character.
That all said, i can't promise you it'll work for sure, and without you specifying which exactly version of Fallout 2 we're talking here - probably nobody would (counting all the various patches, regional versions - which may possibly have this altered as it's one sensitive part of the game, - and things like Restoration projects, Megamod, etc). But it _should_ work, i think.
