If you have the function descriptor, then you know how to call the library's functions. If you have the library, then you know how to determine the offsets of the library's functions. It might be possible to link the object code into yours and call the functions with an understanding of the overall layout; however, if the library calls any of its own functions or any other internal functions, you're still hosed. So, you'd have to decompile the library and go from there.
So, anything is technically possible, but is the benefit worth the cost?
