In SRT Einstein used the velocity v, but meant velocity of an object 
relative to space.

But that definition would violate the very idea of SRT itself.

I meant, that SRT-like movements would require to different 'anchors' to 
measure velocity against like the relation to a target, which a 
cannon-ball hits.

The setting of SRT would actually allow to use other frames of 
references as 'achors'. But in this case velocity v would become a 
variable. But that could (for different v) alter the relation between 
inertia and kinetic energy of a connon-ball in flight, just by choosing 
a different coordinate system, what cannot possibly be the case.
