House of Lords Reform

Paragraph 4.11 of the White Paper states that"““current conventions are the right ones for a reformed House to deal with, certainly early in its life””." If the upper Chamber is primarily or significantly elected, how ““early in its life”” does the Leader of the House expect there to be pressure for a change in those conventions? Would not it be more appropriate to ensure that they are enshrined in law before he rushes headlong into the process of determining how the upper House should be composed?
