Is it easy to get a Rolex 1570 non hacking movement modified to hack?

Just curious..

Ordered a supposedly hacking movement off ebay japan, it arrived non-hacking.

Rather than deal with the return I was hoping there is an easy mod that can be made.

Is there?

You need the balance stop spring and the screw to hold the spring, these parts
are easy to get. But you must also modify the base-plate to fit the stop spring.
I think, that s not so easy :-(
