That works up to a point. But you don't get any feedback, and if MVS is stressed it can ignore commands sent to the console buffer, so it is possible to run the batch job 'successfully' and leave the files open to CICS.
Writing your own tool using EXCI should only take about half an hour or so, and it's much more reliable. Plus you can set a return code so your scheduling software can see if the job worked properly or not. Just remember to set the correct options on the translate step.
