(J) Void or reformed trust in cases of insufficient remainder interests.—In the case of a trust that would qualify (or could be reformed to qualify pursuant to subparagraph (B)) but for failure to satisfy the requirement of paragraph (1)(D) or (2)(D) of section 664(d), such trust may be— (i) declared null and void ab initio, or (ii) changed by reformation, amendment, or otherwise to meet such requirement by reducing the payout rate or the duration (or both) of any noncharitable beneficiary’s interest to the extent necessary to satisfy such requirement, pursuant to a proceeding that is commenced within the period required in subparagraph (C)(iii).
