Precipitate complete breach is normally a 9th level spell with an xp cost and an expensive material cost, so being able to duplicate its effect would actually be a huge upside. Even the lesser precipitate breach is still no joke. Not to mention how much more powerful this rule makes, say, the Blink Shirt soulmeld—a single feat with no prerequisites lets you precipitate planar breaches at will? Seems pretty nuts to me!
Of course, you just made all that stuff up, so none of it seems especially relevant.
