He ask about using Lego block to spread the load out, Legos are hollow with a small edge so they will stack but will more than likely sink as weight is added making for a large Lego divot.
I am fairly sure there is more ground coverage and load spread with the cross blocks than there is with the blocks.
Long boards as you suggested or the cross block I posted are a better option than legos.
I am not sure which blocks OP is using but mine are 8X8 the cross block boards are about 16 inch's long.
