Then the answer is "yes", barely. The photoelectric effect shows
marked effect when the photoemitting surface is heated.
Additionally, characteristic emissions spectra of "stuff" is
broadened by increasing temperature.

But the gamma of velocities associated with even 25000000 K is
not too terribly much larger than 1.

And "photon - particle collision" does require a charged particle
as the particle, and "collision" isn't a very useful term here.
