What about if the Protheans choose or calculated a system, planet and spot where the Conduit could successfully connect with the Citadel.

That is astronomically impossible. With planetary orbits Ilos would probably only line up with the Citadel for a miniscule fraction of the day. With the solar orbit Ilos would only line up once a year. With galactic orbits it may never line up.

Not to mention the huge chance of the target in transit being hit by solar flares, comets, asteroids, black holes, supernovae, stars, ships or planetary bodies. Space isn't that empty.

The London Beam works more like a teleporter than the Conduit does.

Actually based on the loading screen it seems to work like a wormhole, which is probably how the mass relays must work as well - however it also has the same issue as the Conduit, namely that Shep ended up INSIDE rather than being smeared on the outer surface.

It doesn't really matter that they should have been killed in the Mako, the whole premise of Mass Relays are that the work because X effects undiscovered law of physics Y.

Actually most of the game uses a lot of existing theories. However both Conduits fly in the face of any astrophysical basis and are completely unexplained. My point wasn't that they should be killed in a tank, my point was they should never have completed that journey regardless of being in a tank or on foot.

However even with Mass Effects explanation for Mass Relays, there is still no reason Saren was able to survive on foot.

There is no evidence in game he did make the journey on foot. There is also no evidence in game that he couldn't. You are merely assuming that because Shep used the Mako that Saren, Ishan, the Prothean scientists and the krogan troops all used a vehicle, despite the fact that evidence presented in game actually suggests that they did not.
