Not sure about xmodmap but you can modify your
/usr/local/share/X11/xkb/symbols/pc to have the following definition for
Delete key:

key <DELE>  { type="PC_CONTROL_LEVEL2", [ Delete, BackSpace ] };

You can do more research on XKB configuration and how to do the above in
non-intrusive way.
The key thing here is you need to change type of Delete key to
control-modifiable.
