There's no way it would get the requisite 2/3 in both houses and 3/4 of the states, but it would be nice to strip the Senate of its power and make it more of an advisory body like the Lords in the UK.
There are ways to get around that if you really want to. When push comes to shove, the Constitution can be amended with an effective simple majority vote via temporarily admitted new fake states (rotten borough states) in order to increase the # of votes that you have. And there are probably various other ways to accomplish the same thing, which I haven't thought of but that might be more artful.
Wouldn't we then need a majority in the Senate to get these temporary states admitted? Quite frankly, I do not see that happening any time soon...no way Democrats are picking up 5 seats in 2020. 2-3 was possible, 5? No way.
In the end, I'd be on board so long as California (a state that would be temporarily split up, I'm sure) is guaranteed to be reunified once the scheme is over.
