No and no.

The particles destroy any magic they come into contact with, so they would also destroy the magical barrier if you link them, so that's not possible.

And the MBP are not barriers in any way. They are poison plain and simple. They don't block off magic or something like that, because that way they'd only prevent a mage from casting spells. But the MBP don't do that. They kill people without magic even faster than mages and they damage internal organs, as can be seen when Wahl analyses Laxus. So they are no barriers no blockages or anything like that.
