I’m sure you can figure out a way to make it work even though they’re not the ideal size tubs. More stuff in the tub is more to clean and potentially could cause issues if they are able to shift things around etc.
If you’re settled on breeding ASF’s I’d consider a rack like the 99-15 from Freedom Breeder ($1500 range)
Or I’d get a pack of lab mice tubs with a water setup and wire rack from amazon/walmart/etc ($500 range)
The rat lab tubs might actually be better for ASF’s, given more size, versus the pretty small ones for mice. The benefit of these lab style tubs is the way the top is designed the food and water goes down into the tub pretty far allowing smaller animals to feed/drink. This guy breeds ASF’s successfully in the extra large size:
