Try contacting the maker of the transformer. Sometimes you can connect the two secondary windings in series, and do what you want, but at half the current rating.
A center tap transformer is designed to only use one half of its winding at a time, letting the other half cool down each half cycle. The volt-amp rating of a transformer is fixed by wire size. You can't double the voltage out without cutting the current rating by half.
A voltage doubler is likely your best option for what you have....assuming you can get by with 1/2 the amps.
