Detect Bob's mods? Bob's mods adds 2 more tiers of beacon, and you could just say "If Bob's logistics exists, then buff the beacons up" which could end up with tier 9 beacons. Potentially, you could do "If Bob's electronics exists, then add more tiers of beacons" Since the circuit boards are different in bob's electronics. Not only that, Bob's chemicals/intermeds/etc. has chemicals, which could be used for making "Beacon Alloy", A superalloy which can make extremely thin structures. Thus, then you can pack more things into the middle of the beacon, where all the modules live.
