It is definitely possible, but I must think about the performance. :)
I don't know, how long it will be take. Stefan specifies the milestones.
Maybe, it will be included in the next release.
I will be implementing the support from "the outside" since this plugin has noch dependencies to the php plugin (which is good and reduces the scope).
Once #168 (closed) is implemented, I think I can add a lot of value by using the available semantics of typoscript to enhance it with other languages' features.
