I think attempting a lovey is a great idea. I worry about the late introduction too.
Dd had a lovey (well, 2 since I made her a backup but now she wants both at home), but we only ever take one anywhere.
My boys have lovey items too, one a bear and another a weird stuffed dog that he glommed onto around 12 months, lol.
I don't think loveys hinder relationships at all.
