It would be very surprising if the things that fall into a black hole affect the radiation coming out of it.
The reason is that "the things that come out of it" are reference frame dependent. That is, you and I will disagree on what is emitted as Hawking radiation. In fact a free-falling observer will observe NO Hawking radiation!
So Hawking radiation must be determined entirely by spacetime geometry, which depends only on mass-energy-momentum and not things like baryon number.
Oh, and "smoothing things out takes energy" doesn't seem right. Consider the heat equation: a solid with a temperature differential reaches equilibrium while conserving energy.

I mean absent all the exotic physics calculations, since that comment is saying that people are too twisted up in theoretical math. In a very basic sense it seems reasonable. > So Hawking radiation must be determined entirely by spacetime geometry, which depends only on mass-energy-momentum and not things like baryon number. I'm not really following that 'so'. Lots of things are reference frame dependent but still depend on exact particles.
