Can PRO be merge-mined with Bitcoin and other SHA-256 coins yet?

Also, unlimited mining is gonna make quite many people skeptic, as this guarantees inflation and loss of buying power / value over time. I suggest a block reward halving every 2-4 years and no more than 1 billion coins total (after which transaction fees should be the reward), or it can get very hard to trade PRO when it is gonna be worth less than 1 satoshi :/

Think about it!
