While I haven't taken any time to research it or find any scientific cites, practical experience would indicate the answer to your question is no. Even very shade tolerant plants tend not to flower well if located in persistant or heavy shade.

Try it and see! Tie a black hood over some flower buds, and see how they develop.

I suspect one side consequence though is that the un-illuminated flowers won't be able to attract their normal pollinators, so won't get pollinated, and therefore won't develop any seeds.

Also post-flowering, the immature fruit of most plants are photosynthetic, needing light to help produce energy for the seed development.
