It's only over-representation if representation must only be proportional to population.

There is a compromise and a two-sided balance: in the House, big states are "radically over-represented" because of their large populations; in the Senate, small-state individuals are "radically over-represented" because they're divided into more states per capita. Big states/urban areas have the power to block in the House, small states have the power to block in the Senate. The balance is that both sides have enough concentrated power that they're forced to compromise and cooperate or nothing can get done.
Right, it's only over-representation if you believe that all men are created equal.

You're being glib and forgetting important concepts like the tyranny of the majority, etc.
Tyranny of the majority can only be prevented by establishing norms that limit what government can do even with support of majorities in representative institutions either as absolute norms or with some things requiring a higher bar than a one-time majority (bicameralism with both houses not being elected fully simultaneously does this, requiring concurrence between branches does this, supermajority requirements for certain actions does this, Constitutional limitations with amendments requiring supermajorities of states even after legislative passage do this.)
That comment is basically a repetition of your last one with no further explanation or elaboration. It's pretty clear that you have the opinion that political representation should only be proportional to population and that all other systems are bad. We can't have a discussion if you don't want to engage other ideas.
Though, if there was enough support, it could be done with two amendments. The first would be an amendment to Article V, removing the requirement of unanimous changes to the Senate composition. The second would actually change it.
The likelihood of that happening is effectively nil, but it is allowed by the rules set out in the Constitution.
That doesn't remove the problen, it just clarifies that it is a fundamental design problem and not a problem with an implementation details.
> If the Senate is to be reorganized to be proportional to population
That's a bad solution.
A better solution is just to transfer it's quasi-executive powers to the House, and it's quasi-judicial powers either to the House or the Supreme Court (if the House, then some consideration may need to be done of how charging works for impeachment, but that's not an insurmountable problem), and perhaps reduce it's legislative powers as has been done with the similarly problematic British House of Lords.
Or (and this can be combined with the above) rearrange it so that both seats from a state are in the same class (elected simultaneously), and instead of FPTP mandate a two-seat, preference ballot, proportional method like STV for Senate elections.
Besides, you can't restructure the Senate to make it proportional to population (at least without unanimity among the states), as that is literally the one thing that an Amendment cannot do. (There used to be another, but that was time-limited.)
> The current comprise means neither small nor large states can ram through legislation that neglects the other's interests.
Small states are slightly overrepresented in the House, radically overrepresented in the Senate and in judging electoral votes, and overrepresented at a level between those two in the Electoral College.
There's no real compromise or two-sided balance there.
