How accepted is this list?

I know a lot of 40K's experimental rules are so old or so used that they're basically standard now. I like the style of this list a lot, and the wonderous Fleet Defense Turrets'll make not using carriers (which I really don't like much) NOT be a deathtrap. Will I be able to play in tournies (prolly not), or will random gamers refuse to play me (that would suck)?
