Hide item in the ECB menu (Edit Control Block)

Question

First, I would like to hide the "Download a copy" item in the ECB which is found in the document library.
Then I would like to add it in the callout menu.
Can anyone help me with these two steps?
Thank you

Try if this works 
1.    Make a copy of the LAYOUTS folder from “…\15\TEMPLATE\” .
2.    From IIS, make your site collection point to your custom LAYOUTS folder.
3.    Now you can look for CORE.JS into your custom LAYOUTS folder .
CORE.JS
4.    For “Edit in Microsoft Office InfoPath” link, search for “L_EditIn_Text” and comment out the code for “strDisplayText”
5.    For “Download a copy” link, search for “L_DownloadACopy_Text” and comment out the code for “menuOption”
Note: Please remember to keep a track of all changes you do in your custom LAYOUTS folder because for any future releases/ SPs/ Patches, you may need to apply those changes in your custom layouts folder as well. Modifications of out of the box files are
not supported.

Or
If it is not a matter of security you could do it with css:
#ID_DownloadACopy{display:none;}
Or Jquery (haven't tested):
$('#ID_DownloadACopy').remove();
