But the moment right before dislodgement, when the deuteron pair experiences 
considerable deceleration, is precisely when we would expect fusion isn't it? 
So I still believe we must use the CMF of the whole system under study. Similar 
to a hammer-nut-anvil system, if we leave the anvil out of the equation the nut 
will never be broken.

I am pretty sure that COE is not valid in an accelerated frame of reference 
BTW, except maybe in special cases. Consider a single particle in uniform 
motion (constant K.E.) in an inertial frame, it will see its speed and 
therefore its K.E. change in an accelerated frame, so COE isn't verified.

This depends on just how "stuck" the D is to the anvil. Initially at large
separation distances that will be true, however as the force of repulsion
created by the approaching D increases it will eventually dislodge the "stuck"
D, after which, it is no longer true. (Assuming the "fast" D had enough kinetic
energy to dislodge the stuck D).

No, COE is valid for any frame of reference, as long as you stick to the frame
of reference you have chosen.

You only need to take "snapshots", and assume that the functions are monotonic.
(not true at the moment of dislodgement).
