It may still be possible, but then you would probably have to downgrade a whole bunch of packages to their testing versions, including libstdc++6 which will bring lots of packages to their pre-gcc-5-transition versions. I've guided some ppl to do just that, but it was a lengthy (>1 hour) exercise with direct communication on IRC (#debian-kde). Not sure it would be doable or the appropriate place on a bug report. And you may not want to do that for a single package.
