I guess i should do so. 
Having ART in the AUR would be the logical next step. Unfortunately i have never messed with the AUR as a contributor. I guess some additional steps need to be taken before submitting the PKGBUILDs.
I will have a look at this the next days. Any help, especially testing and package review or advise by an experienced AUR packager is greatly appreciated. I’ll track progress in this issue.
