Japanese did not make a new plane, only F-16 modification.
I'm not talking about the F-16, I was talking about the ATD-X:

The intakes can be considered 'ducted' but it's engine is easily
exposed.
It does not matter whether the YF-23's RCS figures were frontal or not; either way it discredits your argument. If we assume it was frontal figures then the entire 'ducted' argument can be thrown out. Similarly, If the YF-23's RCS was an averaged figure then your argument again can be thrown out. Think about it, if 'exposed engines' or none ducted intakes were so detrimental how would the YF-23 have lower RCS figures as compared to the YF-22?
Anyhow Boeing's 6th gen is no really different from failed 5th gen, except the rudder configuration.
Besides a few minor changes like radically different intakes, canards, and V-tails they are identical.
That picture proves nothing
There is little quality photos depicting the SU-24's intake, but this is the best I found:

If you look closely you will see a lower ramp; moreover, the engines are are tucked inwards. Here is a model that depicts this:

There is a huge distance between the testbed and operational plane.
So what is your point? Be specific, throwing vague sentences around proves nothing. A prototype and operational aircraft are more similar then you think. Prototype aircraft test load bearing, weapons capabilities, avionics, and basic flight performance.
A prototype aircraft goes from conceptional design to small scale wind tunnel tests, from there large scale static models are built and put through wind tunnels. This means that an aircraft's performance and characteristics are well known before it even takes off the ground.
what you are suggesting is that the SU-47 was somehow a failure and that it's ducts and weapons bays were sub-par and this is based on....wait for it.....absolutely nothing but assumptions.
How does it matter the number of bays? One big or 4 small, fact that Su-47 had very tiny internal weapon space.
This is truly a desperate attempt to try and argue for the sake of arguing. Try to fit 2 liters of water into a quart and see how that works. You saying that the SU-47s weapons bay is big does not make it so, anyone can pull up a picture of the SU-47s weapons bay and compare it to the f-22 weapons bays and see that the SU-47s bay is about equal in size to one of the f-22s main weapons bays.
