Attani mindlink, although interesting, has been panned, competitively speaking. The ability to share a focus token is undermined greatly by the potential for distributing stress.
But what if the linchpin of your list didn't care about stress, and the other linked ships were built with the expectation of the spread of stress via mindlink?
Overclocked R4 has unlikely synergy with the attani mind-link. Yes, it will spread stress through the link, but it can also spread focus tokens throughout the link multiple times per turn. And the ship carrying the R4 can trigger the bot multiple times per turn without worrying where it's next turn's focus token will come from. (It will come back through the link).
The only ships with an salvaged mech and EPT slot are the jumpmaster and y-wing.
But while we're stacking stress with the R4 unit, why not stack on even more? Zuckuss allows you to Reroll enemy defense dice at a high cost- one stress per dice. But if you are action independent (and effectively riding a glitterstim high every round), you don't care about a little more stress.
For three points plus the cost of other mindlinks, you can have unlimited Zuckuss and R4 triggering. The cost is spreading 1 stress per turn across your list. Managing that cost can unlink some very powerful abilities on a ship... Say Dengar with punishing one. Finding the right pairing for that ship could unlock attani competitively. Maybe.
