Sorry, but that is extremely unlikely. With low-power ARM SoCs, heat is not a major concern compared to other factors --- namely battery life. The A5 is not much different from other dual-core Cortex-A9 chips (T.I. OMAP4, Tegra 2, Qualcomm Snapdragon 86xx) which are already making their way into smartphones. With the constant evolution of process technologies, each year or so should be able to see a faster, lower-power processor.
