So is it possible to use RMAN to backup to disk, then move them to tape
without RMAN's involvement. and when a restore is necessary, use RMAN to
take the backup files directly from tape?

Yes and No.
Yes you can use RMAN to Disk and then use any utility (NetBackup without
the Oracle module, or TAR or CPIO)
to copy that backup to tape.
No, you cannot make RMAN "aware" of the tape backups. Thus, RMAN cannot
restore directly from tape as it
does not know which tape has which backup set. You will have to use your
NetBackup catalog or a manual / scripted
catalog (if you use, eg. TAR or CPIO) to restore the files from tape to
disk (the backup destination location
or any other directory) and, _then_ use RMAN to restore from that disk
location to the database datafiles location.
