The 292 piston is kinda' a one of a kind, and doesn't share any commonality to any SBC pistons other than the bore size. The wrist pin location is what hurts the 292 for any swapping. If you are looking for something for turbo use, then you will need to stay with a dished configuration to keep the compression tolerable. Unfortunately, the cost of custom forged dish pistons is the same for dome pistons, and pretty expensive. But consider it an upgrade and something you will hopefully only have to do once.
