Am actually thinking of removing the whole DG shebang and paving
the area with used brick, which I have some of.

If you're going to lay pavers do NOT remove the DG, it makes an
excellent base, simply lay about 3"-4" of finely crushed stone or
builders sand over, level (screed) and tamp, then lay your pavers and
sweep sand into the spaces. Be wary of the used brick directly on the
ground, it doesn't hold up well to freezes on the ground, red brick
absorbs moisture, many will split/crumble. You're better off using
those used bricks otherwise. Pavers meant to be used on the ground
are made with high density concrete so will hold up well on the ground
