Do you think this will work very well in PvE, especially in heroics from cata and MoP?
Having classes that are able to CC the enemy are usually nice to have when you're unable to overgear instances. This isn't true for every instance, but it was definitely true for Cataclysm heroics. MoP heroics seem to be more forgiving, but can still pose a slight challenge. If you're comfortable with using Hunter traps to CC when need be, then they should be fine.

Account 1 RAF -> account 3
Account 2 RAF -> account 4 and 5

Will all accounts get the 300% XP bonus this way?
If you're going to level all 5 at once, then yes.

Thanks for taking your time
Assuming you're not using a 5 year old video card, playing at some super-high resolution like 1600p, or wanting to play at Ultra settings, then I don't see why not.
