Though this proposal has been ruled out, I wouldn’t give up hope that we could eventually construct something with a much larger cross-section for neutrino interactions than ordinary matter.

In my story “Wang’s Carpets”, which became a part of DIASPORA, there is some hand-waving about excited nuclear states with this property [and which are kept from decaying too soon to be useful by employing the quantum Zeno effect].
