This may not help you any, but at least it might get some discussion going. Following code exports two schemas, each directly to a compressed disk file. These could then be sent to tape with fbackup.

mknod mypipe p

compress < mypipe > ap.dmp.Z &
exp ap/ap file=mypipe 2> ap.log

compress < mypipe > gl.dmp.Z &
exp gl/gl file=mypipe 2> gl.log

So, are you wanting somehow to send several compressed exported schemas directly to tape, rather than first to disk as above?
