Could a miner who wanted more transaction fees manipulate the fee produced by estimatefee? If so, what percentage of hashpower would it take, and how long would you need it?

No, estimatefee is calculated locally by bitcoind in function of some statistics done on mempool.

Ok, but those transactions are received from remote nodes, right? Commented Jul 4, 2015 at 1:53

ye, but not from a single node. A miner can't change your estimatefee behavior. Commented Jul 7, 2015 at 20:41

Miners can change your estimatefee behavior. For example, they can accept very low fee transactions. Commented Jul 7, 2015 at 22:15

In your question you are talking about "a miner", and the answer is no, a single miner cannot do this. Commented Jul 9, 2015 at 0:35
estimatefeeworking as intended. Most wallets currently pay a flat fee per kilobyte, so I doubt much research has been done into it thus far anyway.
