There are three genomes that go into an embryo. One from the chromosomes of the large gamete, the egg, one from the chromosomes of the small gamete, the sperm, and one from the mitochondria, in humans from the egg as well. If you had two XX donors you could make XX kids. If you had two XY donors you could make XX, XY, and YY variants. The only viable ones would be XY and XX, YY would not reach gestation.
That said, if you took the DNA from gametes from each, removed the nucleus and mitochondria of an egg, added the total gametic DNA from both to the cell, added a mitochondria from either donor, then it should, in theory, be a viable egg like in IVF. This is actually a strategy for dealing with a mitochondrial disease by donating mitochondrial DNA from another source rather than those impacted by the disease. The problem would be there are many ways for this to go wrong and be left with an unviable embryo, so it would likely take many many eggs and many many donated cells to get a single viable egg with the donated DNA. That said, it could technically work.
There are a number of less optimal combinations, as well, such as XXY, XYY, and XXYY.
