Well more to the point, in order to use the insurrection caluse he would have to actually be found guilty in a court of law, a **federal** court of law, and possibly need to be impeached by congress itself. But regardless someone at a federal level would have to make that ruling.
That said, the 14th amendment specifically says "incite". So assuming they can prove he incited it then they could have a case. But they do have to prove it.
