Actually, I'd be more in favour of tweaking the Child's Dex up to a +3 bonus and dropping the NA bonus since it means the undead will have the "naked" AC of 10 when flat-footed and be 2-points lower than the Maidens like in the original. If you prefer AC 17 I'd be willing to make the Dex bonus +4. We did give the Veiled Maidens a Dex of 19 rather than the original's 15 after all.
Incidentally, I'm developing a nasty suspicion the original Veiled Maidens might have had Intelligence 8 rather than 18. The Stat line could go "S 15, 18, W 15, D 15, C 16, Ch 16" or "S 15, I8, W 15, D 15, C 16, Ch 16" and I just can't tell whether it's a missing space between an "I" and an "8" or a missing I before an "18".
In AD&D Monks have minimum attribute requirements in Str, Wis, Dex and Con but not Int and Cha, so Int 8 is quite possible. There were a lot of dumb and unlikeable monks in AD&D games due to this!
Since there's no way to tell which is correct I am happy leaving those undead girls' Intelligence score at 18.
