What Black Holes Are Made Of?

Wikipedia says Planck particle "defined as a tiny black hole whose Compton wavelength is equal to its Schwarzschild radius".

Can we really think of Planck particles as tiny Black Holes themselves, as Wikipedia says? I think the answer is yes. Then, could we also really and truly call them Black Hole particles? I think the answer is yes. Would it be logically consistent to say, Black Holes are made of Black Hole particles? I think the answer is yes.

Would that be consistent with General Relativity? I think the answer is yes. Because, would it really make any difference from GR point of view, if we divided a single Black Hole into N smaller Black Holes? Would the total gravitational field around of that Black Hole, would really change then? I think the answer is no. (Actually, the total gravitational field around of that Black Hole would be locally different from the total gravitational field around of a single Black Hole, but it would become more and more similar/indistinguishable, as N increases toward infinity. And, if Black Holes are really made of Planck particles, then N would be an astronomically large number for any real Black Hole, and so the gravitational field around any real Black Hole (made of Planck particles) would be practically indistinguishable from the gravitational field around of a single Black Hole.)

Would that be also consistent with Quantum Mechanics? I think the answer is yes. Because, if we are assuming Black Holes are made of Black Hole (Planck) particles, then we are assuming Planck particle is real and so it is a (new) member of Standard Model. And if we are assuming that, then would it be consistent with Quantum Mechanics, if Black Holes are made of Black Hole (Planck) particles? I think the answer is yes.

And, if any theory of Quantum-Gravity (now/future) is really correct, would it not say that, all objects in the Universe (including Black Holes) must be made of particles? If so then, should not we consider, which theoretical elementary particle(s) we know about, could be really fully consistent with, what we know about Black Holes and GR and QM, altogether?

I think only a particle that is by itself a (tiny) Black Hole would be consistent with General Relativity, for BHs could be made of. Is there any other theoretically possible particle that is a tiny Black Hole itself? I think the answer is no. So if any Quantum-Gravity theory is correct, and so BHs are made of particles, then only valid possible option would be Planck particles.

So, I think the idea that "Black Holes are made of Planck (Black Hole) particles" is actually consistent with both Quantum Mechanics and General Relativity. Can we say the same for the idea that "the center of any Black Hole is a singularity"? It is obviously consistent with General Relativity, but, is it really consistent with Quantum Mechanics, also? I think the answer is no. Because, Quantum Mechanics (Standard Model), does not, also cannot, have any elementary/composite particle that can represent a singularity!

So, it seems to me that, it is physically/realistically more plausible, Black Holes are made of Planck particles, compared to, Black Holes contain a singularity in their centers, which has infinite density and zero size and can have/hold any amount of mass/energy/information.
