It is possible, but what is the point of having RMAN backups when your only one instance crashes. How you are going to restore the instance in order to use RMAN to restore your second database?
You better create another db instance for RMAN, setup RMAN to backup your primary db, and then do full export on the RMAN db. This way if RMAN db instance crashes, you restore from full db export (RMAN has small footprint), if primary db instance crashes - use RMAN to restore.
There is no advantages of using one db instance to store data and RMAN catalog...
Hope that helps,
