It's off-topic.
It's an interesting question, but it's off-topic, and too broad.
I wrote up an answer here that's mostly a justification of why it's too broad, but I was hoping to post an answer to the question before it got closed.
The crux of it is that information hiding, clandestine activity, pseudonymous navigation of the web, etc. are all "cat and mouse" games.
For any measure that you take to safeguard or conceal your identity (which is effectively the same difficulty and same strategies employed as having two false identities, so I'll treat the two the same), there is an effective countermeasure. Similarly, for every countermeasure, there is an effective counter-countermeasure that you can take to defeat that countermeasure. This goes on up to infinity, depending on the resources you and your adversary are willing to invest. There is literally no end to this identity-finding and identity-concealing arms race.
Therefore, the question
Would this be enough?
...is eternally unanswerable.
Or perhaps, to take the tinfoil hat user's perspective, the answer is too simple to be worth posting:
No.
