Kimmo,
A ToE is very ambitious. I am a believer in an Aether. To me, the question is simply what properties must an Aether posses in order for reality to be as it is observed.
I have received many rejections for papers ... usually they are just the standard crackpot letter ... no surprise. Occasionally, the editor will actually include a helpful comment. The position taken by science is very straight-forward. Can you explain something that was previously not understood? Can you make a prediction that can be falsified? What does the idea add that science does not already have. Bear in mind that a new idea must also satisfy everything that is already known. It is very difficult!!!
If the answer to any of these is weak then why should anyone consider the idea? I don't fault the gate-keepers for this. They must be very careful in guarding their credibility.
Having said all that, your idea is interesting (to me at least). But how do you account for the mass ratio between the proton and the electron if you think a proton is composed of three electrons? BTW, the mp/me mass ratio is ~1836.15. Also, keep in mind that spin and charge are conserved. Of course, you probably handle that with a combination of an electron and a positron.
Stick with it.
Best Regards and Good Luck,
