Gravity's Strength in Galaxies: A Quark-Like Explanation?

[kurious]

Is gravity so weak because every force mediating boson starts out as a graviton, which then loses energy and becomes gluons,photons W and Z particles.
This would mean that the graviton carries colour charge and so dark energy
must emit gravitons with colour charge and therefore dark energy would by implication be quark like in nature ( and so would neutrinos - perhaps they are light neutrons made of three quarks).If a proton's mass could form a mini black-hole that black hole would have a temperature of 10 ^ 51 Kelvin.
The fundamental forces of the standard model unify at 10 ^ 32 K so the temperature of the radiation emitted by the mini black hole would be sufficient for us to say that all forces were one force and gravitons can be the sole mediator at the outset.
If dark energy particles are quark -like then they would also have an electrical charge ( half of them could be positively charged, half of them negatively charged)which a magnetic field in a galaxy could exert a force on and so squeeze them together increasing their density and the force they exert on stars they collide with.Is this why gravity seems to be stronger in galaxies than it should be?

I strongly believe this is impossible. For starters gravitons (which are still hypothetical) have the wrong spin and most likely are less energetic than any of the others.

Photons have spin 1 but can yield 2 spin 1/2 fermions.Gravitons might yield 2 spin 1 bosons.Spin is no grounds for an objection to the idea.
There is no proof of how energetic gravitons are when they start out.
