In my opinion, no. All that will happen is that you might have to answer a few extra popups, for perceived (or genuine) malicious behaviour.
I would say your level of protection is extremely good. No need to overdo it.
(That said, it assumes that Outposts' HIPS is OK, a good one. I don't actually know. HIPS in general, working correctly, and correctly responded to, are powerful security tools.)
