They won't be centertapped.  I can't vouch for the typical current ratings 
but if that is high enough and if you can find two identical units you could 
series the primaries and series the secondaries and get 5 VCT from 120 
input.  For symetrical strays to ground characteristics, connect finish to 
finish and finish to finish (primary and secondary) rather than finish to start 
and finish to start.
