No, loose vermiculite won't work, it's fluffy, and will push right out of the way, or compress to uslessness if you tried. The portland makes it into a rigid layer under your oven floor which can't move or sag at the risk of cracking or worse.

If you don't want to mess with the vermiculite concrete, use a refractory insulation board.
