It is possible--modified viruses are used as carriers, or "vectors" for
genetic material from other organisms all the time in molecular biology
(notably bacteriophage and adenovirus, but others as well, including
vaccinia virus, which is related to smallpox virus). However, researchers
would have to know the entire genetic sequence of the Ebola virus, know
which gene(s) is/are responsible for infecting and attacking the body, and
know how to splice it into the variola genome correctly to maintain the
integrity of the relevant genes from both organisms. And, they would have
to show that the recombinant organism would act as postulated (contagious
as smallpox, deadly as Ebola) without one inactivating the other, or the
combination having even more nasty attributes. Theoretically it's
possible (the show Millenium had that premise at the end of last season),
but technically it's quite difficult.
Speaking of smallpox, some infectious disease experts believe smallpox is
poised to make a comeback. It's been 20 years since the last known
naturally-occurring case and routine immunization against it has
stopped--meaning a whole generation is completely unprotected against it.
