You need freshly fused KHSO₄, so i'd suggest you make it yourself:

KOH + H₂SO₄ ^__> KHSO₄ + H₂O

I see no immediate reason why NaHSO₄ couldn't be substituted here.

KOH and H2SO4 often have small amounts of water present... KHSO4 likely also picks up water better than NaHSO4.

I'm not saying you're wrong or anything though.
