It would take a good bit of work to do cement, digging, leveling, sand, gravel, forms, tamping. With a continuous concrete slab things shift over time cracking a large slab. You could make smaller slabs with a 2 X 4 frame in smaller squares like 12" x 12" with all of your pieces set in them, making smaller stepping stones. Dig to a depth to bury you slabs in and pour pea gravel and tamp lightly. Use a base of felt paper sheeting that you use for under shingles on the roof and put your sand on top of that, then snug your concretes squares you made on top of that into the sand so they asre level with the surrounding dirt. The felt paper helps the sand from flushing away and the sand lets the concrete shift on it's own with less breakage when the weather changes. they are easy to straighten simply by lifting and shifting the sand to level again.

Lift up existing stones, Firm ground Peg out line of Path and section it to make workable areas. Start at the furthest from the house. Mix and lay concrete , allowing for the tiles/slabs etc to be added with a mortar mix later. Continue in this manor until all pathway has been concreted. Dividing it into sections allows you to be able to do as much or as little in one go as you wish. Once concreting is complete leave to cure, then start at the farthest point again and lay on a mortar mix the tiles /stones /slabs etc. (This can be done in one go, but doesn't have to be. Leave again as long as you can to cure, then remove the Shuttering you pegged in and put the earth or Back in place. That's it......

Trace around the stones with spray paint. Then remove the stone and dig down until the stone will be ground height. Put the stone back it should not move now.

Agree with what both Em and Johnavallance82 said. Yes, it is a lot of work, but sometimes there is no alternative to doing a job the correct way if you want the results to last over time, to be durable, and to look attractive.

Thanks all! Have to rethink my plan. Really sounds like a lot of work...

1) dig up everything that's in there, correct anything you don't like about the path of the path, and level the depression (now is the time to think about drainage if water tends to pool around this area) . figure out a standard thickness (based on the thickest pieces) create 'paving stones' using the thin stuff (either mosaic on bought pavers, or pour your own, embedding bits of crockery) let them cure, lay them in the path, and backfill with paver (polymeric) sand.

2) same process, but build a series of forms, pour a form, embed stuff in the wet concrete, let set, repeat

3) find a pro willing to work with your bits and pieces (you can lay out mosaic patterns, cover the faces with contact paper, and make a fairly easy transfer to the wet concrete)

Thank u, Jean, for your detailed suggestions! U gave me hope ⛙🔥
