I'm pretty sure you're being sarcastic but I think realistic option would be to implement a weighted voting system based on time spent as a resident of the area the vote is for. Want to move to our state, your vote is worth 1/10 when you arrive and gorws by +1/10 on the next calendar year eventually topping out at 1/1. Want to move towns within the state? You can keep your voting power in state elections but you're gonna restart from 1/10 for local elections.

This would put a stop to hordes of new residents from trashing places because it would give the existing residents time to react before the newcomers dominate local politics.

Experience/time considered in all sorts of contexts. The opinion of someone who's been doing something for years is more meaningful than that of someone who hasn't. Why don't we apply that to political representation. People who have been living somewhere for awhile probably have a better opinion on the future direction of that place than people who haven't.
