It's been discussed on-wiki before and firmly rejected (too lazy to dig it out). There's no way around needing a human pair of eyes to look at what a new user is up to and judge how best to welcome them to Wikipedia editing or advise them on problematic contributions.
Twinkle has a well thought out set of standard welcome templates built in and if someone wanted to create a better intelligent welcomer user script, I have some highly successful code at <http://en.wikipedia.org/wiki/User:F%C3%A6/vector.js> [under "function myWelcome(mytype)"].
