Accidentally created local df in RAC

I've got a potential resume-faxing situation in dealing with a 20+ TB db. This is on a 6-node RAC, Oracle, RHEL 4.x, ASM, OMF.

I added a datafile to a tablespace on node1 and unfortunately forgot the plus sign in front of the diskgroup. We use OMF so what happened is instead of a datafile getting added to ASM under <diskgroup>/<db>... it created one on node1 under $ORACLE_HOME/dbs. Of course the other 5 nodes started complaining about ORA-01157 errors. I saw this right away and quickly offlined the datafile. Now the datafile has an ONLINE_STATUS of "RECOVER".

Unfortunately the database is in noarchivelog mode and also critical production (odd combo, I know), so I'm paranoid on trying anything further. My thought is to use DBMS_FILE_TRANSFER to put the datafile in ASM, then do a rename and bring it online. Is that the best method? I'm pretty sure nothing got written to the datafile as DBA_EXTENTS shows no extents in that FILE_ID.
