I've been thinking for a while that it would be cool if we could replace the Lotus with other characters for mission directive voice lines, but the events of Sacrifice somewhat clinched it for me... we need it. The idea would be that, by default, you can keep the simulated Lotus for your mission directives, but you could customize it from within your Orbiter to pick from alternative characters to fill the role. The options already accessible could be, say, three different "Tenno operatives"
