Tricky but you will probably hear our loud applause if you pull it off

As to slinging the load why not bend some rebar into loops and hook around the internal rebar. Extend the loops above the slab and put straps through the loops to move the slab.

After the move cut off the rebar loops.

sounds to me like your plan is a whole lot easier than building formwork around the top of the stand. When you pour the supporting slab it is a good idea to slope it slightly downwards towards the corners ie a hump about 1/4" higher in the middle, to avoid water penetrating between the supporting slab and the insulating slab.

Sorry guys...The 'Poor Choice' comment was in response to brickie's very concise..."it'll melt" regarding my mention of possibly using foam below the hearth....oughta know better, I've been lurking long enough!

Thanks Al..!

Gulf & Chip you both have pointed out a practical option, that of installing something in the hearth base pour to accomodate the 'load in' ...Chip good thought, maybe three stout eye bolts that I can take the trusty sawzall to after it's in place.......Keep up the good work you guys.....I appreciate your critical eye!

David, that's a good point. One of my future posts was going to be a question regarding how you all handle the inevitable seepage or accumulation of water under your hearth. While I can imagine a little dampness might be OK, standing water could be trouble
