We agree that it's best for the pots to not sit in the collected water in the saucer. A trade-off might be to keep using saucers but find a way to elevate the pot base above the water line. "Pot feet" are one tool used to keep pot bases off the ground, and might be useful here, though they might necessitate some creative placement so they don't require a larger saucer to accommodate their spread. Pot feet are just risers that hold a pot up about an inch or two above the surface, and they can be made from glazed ceramic, terra cotta, or plastic materials. (If you'd be worried about a tipped-over pot letting the plastic pot feet blow away, then ceramic or terra cotta makes more sense to try.) They tend to come in multi-packs of three or four "feet" per package, and many garden centers sell them alongside their ceramic pot inventory. (Bricks or pieces of similarly-sized, flattened stone would work just as well, though would take up more room beneath the pot and might obstruct a drain hole or just not fit well onto a saucer.)
