Poxvirus recombinants are also made using this method.  There are a
number of genes that have been used for positive selection - gpt,
neo, hygromycin.  Also beta-galactosidase has been used a
reporter gene to identify recombinants. Besides homologous
recombination to make recombinants in vitro ligation is also a
suitable method to make recombinant poxviruses -  as long as there is
a suitable helper virus to rescue the recombinants (naked poxvirus
DNA is not infectious).
Good luck
