I honestly think that is, without sneering, utopian. The political establishment would very soon find a way to get a grip of candidates. A fixed term would allow members (Lords?) more freedom to defer from party policy, and proportional representation would result in a more representative house, maybe even more independents? Ideally there would be no "whipping system", although I am not sure how that could be done! The most important aim must be to avoid it becoming an echo chamber for The House of Commons. One great advantage of an elected system is that it would prevent long standing (sitting) MPs who have been rejected by their constituents from being "booted upstairs'.
