I don't have expertise in this, but wouldn't it be that your chance of mining a specific block doubles? I don't believe it would affect your overall profitability, because in the inverse case of the amount of miners doubling, if you lose out on a specific block, you can just start mining the next one instead, so on average it should be the same. And you don't lose out on work because of the high randomness of winning hashes.

With only one winning block (generally), yes your chance of mining the specific winning block doubles. There is no explicit co-ordination regarding blocks mined, and no hashes tried by other miners have any impact on you or your odds, except if they win, as there is no (known) co-ordination between (independent) miners on what has or has not been tried yet - any block which produces a valid next-in-chain value is the 'right' one, and every miner who gets a value which isn't the right one, got a wrong one.
