Thats highly unlikely, because just as colonel kurtz said, even if the numbers of the chromosomes add up, and an offspring between two different species are produced the offspring will be disabled in one way or an other, most often sterility or deformities in the internal organs causing it to die within days.
So while you are right on that most homo-species would be able to produce offspring with mankind, it would most likely lead to sterility.
In fact, thats one of the theories behind why some homo-species died out so fast: Because they started interbreeding with other homo-species causing sterile offspring.
But a human cant fuck a monkey and get a homo erectus you know.
