Yes, this currently isn't possible (AFAICT), because of how the
http_rewrite_module's phase handler works, but it should be possible
with easy modification of that, which will allow for recalling rewrites
after subrequests. I'm busy with other stuff right now, but I'll try to
build the generic interface (if not the subrequest part) soon and
include it in the first launched version of the NDK.
