It's quite possible, although you don't want to use connectors that allow for
cross connection, want to make ground and power first since some toys don't
play nice when they're powered off, and probably want an electrically separate
(Symbios makes repeaters for this, or you can use one SCSI channel per device)
chunk of bus for each device.

Leaving unpowered devices connected is a bad idea.
