Sorry to say, but all objects in our universe form out of large balls of gas and dust or are an end product of the formation of these. Black holes are only formed under extreamly dense conditions. So dense that there are no known forces (pressure) to counteract gravity to prevent the object from collapsing upon itself. There are only 3 ways they can form, from the big bang, the death of massive stars (about 8 times the mass of our sun) in Super nova explosions, and at the center of many galaxies.

The problem with your idea is that a black hole never "fills up" as it gathers more mass (it dosent acually suck like a vaccume, it works by gravity in the same way as the Earth, Sun any other object with mass.) Once somthing becomes a black hole, there is really no way for it to be reversed because the density is already past the critical. They can, however, evaporate, but it involves some quantum mechanics. (Stephen Hawking proved this.) Matter anti-matter pairs can spontainiously form and recombine (this dosent violate any laws as long as it follows the uncertainty prinicible) but one can fall into the hole and the other can fly off. Matter inside the hole must then be "erased" to allow the other partical to exist. Somthing along these lines.
