Uplifting Lesser Spren via Hemalurgy?

[Trusk'our he/him]

If you were to go to the cognitive realm on Roshar and implant one or more Hemalurgicly charged copper spikes into a lesser spren, could you grant it sapience? Would you then be able to bond it like a radiant spren? Would it be easier to bond because of the holes in its spiritweb?

[CryoZenith he/him]

I don't know for sure what the answers to your first and third question are, but the answer to your second question is most likely no. There is something special about radiant spren which allows them to be bondable. Sapience on its own is necessary for bonding but not sufficient.
