Possibly, although hotter fundamentally means more thermal noise, which might actually reduce correlations / ability to communicate effectively between adjacent circuits.
Think of it as SNR (signal-noise-ratio) -- increasing temperature increases thermal noise (there are other kinds), and with the same signal, it should actually reduce the efficiency of the side channel.
But it brings up a good question, I wonder if anyone has studied this...
