Great to see you interested in this topic. A few notes:
* Doing a UNO Remote Protocol (URP) bridge might be easier than an FFI
bridge in that you do that in an external, purely Haskell process (and
the documentation of URP might be somewhat better than the documentation
of Binary UNO, which you need to interface with in the FFI case). In
the end, a "real" UNO binding would support both, but it would of course
be fine to concentrate on one of them, at least initially.
* FFI being C rather than C++ should not be a problem, as the Binary UNO
code that it needs to interact with is just C (although partially
implemented in C++). (One UNO concept is the "Binary UNO hub" that
bridges between different language bindings, which each provide a bridge
between that language binding and Binary UNO, so if e.g., some C++ code
calls a UNO method implemented in Java, that call goes via the
C++-to-Binary-UNO and then via the Binary-UNO-to-JNI bridge.)
* You mention Python, but I wouldn't make a bridge between Haskell and
PyUNO, but rather between Haskell and Binary UNO. I see no advantage in
the former, just more layers of indirection that complicate matters.
* Great to read you already did a LO plugin. Is the code available
somewhere to have a look at it?
* To be eligible for LO GSoC, you'd need to do some Easy Hacks first.
* Do you also have experience with Haskell itself?
