To understand my question, let me draw you to the sample sentences I bring from another post: Usage / examples of "of which".
- She discovered so many spiders, of which she was most afraid.
- He answered all the listening and reading exercises, of which the test mostly consisted.
- The team won a silver medal, of which they were very proud.
In all of the above sentences ending words afraid, consisted, and proud are split from of in their normal usage, (e.g. afraid of). Is it still valid to proceed beyond these ending verbs like these :
- She discovered so many spiders, of which she was afraid more than anything.
- He answered all the listening and reading exercises, of which the test mostly consisted as he has predicted.
- The team won a silver medal, of which they were most proud due to their hard work.
