I would not go this route at all. In previous edition, it was a limiting factor for the fact that elves had:
1) Long life spans. Ridiculously long. This enabled them to use some spells without restraint such as haste, limited and full wishes without fear of the consequences.
2) Could multiclass in the most powerful class (MU) without losing anything in the process. In fact, MU/Thief was one of the strongest multiclass. A grey elven MU/T could go as high as 18/infinite and keep being relevant through out his/her career.
3) Elves started up with a lot of bonuses compared to other races. Just the enhanced surprise possibility was crazy when in the hands of a thief. Secret door detection and quite a few others.
It was because of these that elves could not be raised. Reincarnated yes, but not raised. In 5ed, they no longer have this strong advance that they had in previous editions. Limiting them, although great lore wise, would no longer serve any game purpose and could refrain some players from making elves. Unless you give them something worthwhile in exchange, I would not go this way.
