If a bunch of wall warts is your only problem, you can solve that by using one larger power supply (same voltage, higher current) and wiring all the units in parallel. Although even though it would be in my wheelhouse, I've never really done this for production - it makes it harder to change the setup and more prone to error (reverse polarity and the like).
