I've seen comments that indicated that ART was tuned for Qualcom CPUs and wouldn't deliver performance advantages on Tegra3 (N7 2012) or Exynos (N10).
OmniROM has it available on both but I've never bothered to compare and it may actually be pretty difficult to do.
The data partition is separated from the system partition, therefore the only way to solve the no space would be repartition the device, which is a risky procedure. For example, my Galaxy S4 was a 16GB device, with only 9GB available to the user, because the rest was taken by system and cache for example.
