That would completely defeat the purpose of limited availability. It would demean the LE characters and the people who earned them. I am not opposed to limited release of heroes (That's how I got Emma Frost) they should not make them available all the time.
I wouldn't be surprised to see them doing it as soon as their so called 'season 1' is finished. I thought PVP heroes were going to be Limited Edition, but turns out you get them a month in advance. So if they do release them, I'm sure they'll be set at 200.
