They aren't that different. I'm running 8.11 SP1 (not standalone) and on the development workstation it looks like it could be possible to do what you suggest.
Look at my jde.log after starting 8.11 and then bringing up the "EnterpriseOne Menu"

I have these entries in my local JDE.INI:

I can also telnet to port 6013 and see that it is responding. Technically, it could be possible, but I can't guaranty it will work with Xe...
