So, in Python they're represented as Boost.Python extension instances
containing instances of your widget classes (?)

If I understand you correctly, whether it would work or not depends on
how sophisticated SIP can be about unwrapping a Boost.Python extension
instance and retrieving the underlying C++ object. I doubt SIP has
this ability built-in, but it may be possible for you to add it.

That doesn't prove much of course. Most simple test programs cause
Segmentation faults ;-)

I have no such knowledge.

Hard to say without knowing a lot more about SIP.
It seems like there are two obvious approaches:
1. Get Boost.Python to wrap your objects in a way that SIP already
2. Get SIP to understand the way Boost.Python already wraps objects
