I do not see how Sybil attacks relate to my question. The adversary will simply set up new nodes, without messing with attacking identities of existing ones.
It will not go quite unnoticed when the set of major relays changes substantially over a few months.

That???s $1million a year to control most of the Tor nodes., You call this "costly"? This amount is a joke, a trifle, petty cash for any US or Russian government agency. FIFTY times this amount is STILL petty cash, so in case you think $20/month is not enough to run a relay, make it $1000 a month.
This assumes that there is only one entity wanting to do that. When there are multiple the game isn't that easy.
