Is it possible to use a list of values from a views display as exposed filter of another view?
To do this, 

Install the entity reference module. 
Create an entity reference view (like creating a block or content pane). The results in this view will be your exposed filter.
Create an entity reference field in your content type.
In that field's settings, select the above view.
Use this field as an exposed filter.

Without more detail, I can't really describe how to set it up accurately but this is generally the accepted method.
