Is the strong force ‘just’ electrostatics?

I read this paper today like a breath of air.

What if the electron is not a single negative charge, but rather an onion

like arrangement of charge, with an excess of 1 unit negative?

Same for the neutron and proton (instead of 1/3 charged quarks).

Have a look at the image on the right. We see a ‘strong’ force holding these particles apart.

Could this be an actual model for real particles? I don’t think that the author of the paper intends for this model to be taken literally, but it certainly has some obviously interesting properties. Intrinsic Charges and the Strong Force.
