Lords? The USA has one Senator per state. Four is too few - couldn't fill the ceremonial post - but if you count the counties (England 48, NI 6, Scotland 33 and Wales 13) it comes to a round 100 which seems a sensible total. Then some non-voting hereditary peers could be added to fulfill the additional ceremonial roles and honorary peers who could give speeches to advise could be added for their expertise and as an award, but strictly limited in number - but not with a vote.
