yes you can, it will involve modifying the FPE file of the object you want to do this with.
If you open the FPE of the Health object, you will see a section called
;identity details
isweapon = 0
isammo = 0
ishealth = 1 <----- this is what your new health object's fpe file needs to look like.
isimmobile = 1
These can be edited in Notepad.
Then you can use the same script, and it should work for you.
Let me know if you need more help.
