What about this approach:
1. you compile and add a new word e.g. sinus4
2. you check whether the same name does exist already (e.g. sinus3)
3. you replace the header of the older word (sinus3) with a simple jump
to the new one (sinus4).

It will be built into compiler. So every call to an older definition
of the sinus from whathever word previously defined will actually call
the new one. Thus upload of new sinus will affect all previously defined
words.
Of course you must not use marker, otherwise you may loose the track.
However you may redefine marker so it reconstruct jumps to the older
versions of the sinus4.
