I mean that there should be no possibility to access the WN from outside
using some unknown to me features of twisted.
It is better to strip off the software from unnecessary functionality.
The worker node should (in my view) be able to execute sage and python
scripts. Everything else is not needed.
In the term of "safe" I put stability of use by many users in the system
which is not going to stall the machine.
So, as it comes out of your question there is no point to do anything
with Sage to install it on worker nodes. Might be the only thing is to
pack it into rpm for Scientific Linux.
