You can do this, but you need to be clear on the precise aim, and check your hardware.
From what you've said, it sounds like you want to have two separate systems. One is running JIRA Software and the other JIRA Core. They are totally independent of each other, but just happen to be installed on the same server (ok, application links may happen or hooking them up to the same external applications, but they're still separate systems)
You'll need to install the second system in a different location on the disk - for both jira-installation and jira-home directories. They can run as the same user, but you must be careful to point to the different directories (set JIRA home in setenv.sh for example). They will need different URLs, and you'll need to change the port for one of them (look in server.xml)
Finally, resources - will the server have enough CPU and memory to cope with two JIRAs (not forgetting space for the OS)
