What is already ported is the fontspec package so that the font selection macros from the users point of view are (almost) portable between XeLaTeX and LuaLaTeX. XeTeX can do a lot using TECkit maps. They are not available in luatex, but an equivalent feature could be implemented in lua. Switching from XeTeX to luatex will not be easy, so if somebody decides to maintain XeTeX, it will be certainly better. However, I should mention that XeTeX files are not that portable. A few years ago I developed a set of macros for typesetting the Prague Bulletin of Mathematical Linguistics. The editor asked me to help them with the first issue using these macros (and with conversion of a few manuscripts from Word to TeX). I did it in Linux, they used Mac. They had a different version of DejaVu fonts and the result was that on my computer the issue was one page shorter. Finally they had to use my version because at that time XeTeX had Macintosh specific bug and the document did not compile. Later they found that fi and fl ligatures in DejaVu fonts on Mac are missing but are present on my Linux computer. They had newer version so finally they decided to downgrade their DejaVu fonts to the same version as my Linux version. I have different Linux versions on my computers and in some of them the Nafees fonts do not work properly. Anyway, XeTeX is a useful and powerful tool but you should be aware of such problems.
