I was wrong both abilities do stack, but they were nullifying each other.
I hadn’t try with ships in the system but no in the same sector.
My shields were increased by stacked shield modifiers, while enemy shields were unaffected.
The problem is that as their names state the shield modifier affects the whole system while the shield disruption only the sector.
I think that the best solution would be to forget the fancy abilities and just make it a powerful shields-only weapon.

And again, what do you think about colony ships?
