Sorry, no.

This does not work, because the 2nd DEVICESCAN has no effect:
 From smartd.conf(5):
"If a non-comment entry in the configuration file is the text string 
DEVICESCAN in capital letters, then smartd will ignore any remaining 
lines in the configuration file, and will scan for devices."

I guess no.

-d removable itself is not experimental, but this new feature 
"[NEW EXPERIMENTAL SMARTD FEATURE] A device name is also ignored if 
another device with same identify information (vendor, model, firmware 
version, serial number, WWN) already exists."
