Perhaps at least half-answering my previous query...
This is what I recently bought - the die-on-board version:http://www.ebay.com/itm/221670209239?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

Anticipating this interface scheme will work:http://www.crompton.com/hamradio/usb_fob_modification/usbfob_interface.pdf

we may be able to extrapolate some updates... I did verify the pinout of the 108 and 119 chips are the same.

Regardless of direct/specific pin access, if the controls/indicators are assumed the same, access to the associated signals should be available at the respective (VolUp, VolDn) switches and Red LED.  
The audio jacks are through-hole mount.  Potentially removable and place DC blocking/coupling caps in the dongle, as well as the PTT output buffer, and perhaps any buffer for the active-low CTCSS and COS inputs.
To make a little more space and not chance an erroneous, unnecessary button press, clip the actuator posts and glue the button tops in place.

It may be a few days before I can get to the necessary 'surgery', create a new node and test, but this looks to have potential.
