Why not? We've had demolished golden horn chain mechanism in Revelations, changing flags in Nassau in Black Flag, and even snow in Masyaf.

I rather doubt it would be that complicated to add a spawn script for a simple static object like a lamp, duplicate it loads of times and give it lightsource parameter. Would also look really neat if halfway through the game you see lit up streets, where there was drab darkness before.
