What you can do to get rid of duplicate CSS IDs is to configure your custom view to "Don't use layout for this view
" (under View's menu > View Properties).
The only issue then is you will need to add a wrapper <div> around all of your embedded views like this:
[DFR:My custom view?word=coca cola]
[DFR:My custom view?word=foobar]
[DFR:My custom view?word=qwerty]
