The real problematic code is in PyKDE4, to be precise the kpythonpluginfactory (kpythonpluginfactory/ directory in PyKDE4) which is at the moment Py2 only. If that can be adjusted (I have no idea if it can, since I'm amateur at best at C++) then we can think about making plasma and such Py3 compatible.

I would be in favor of using eval, BTW. I would like to have Py2/Py3 compatibility (the rest of PyKDE4 is in fact fully Py3 compliant).
