Etim 6 clasification in Hybris 6.x

One of our clients need to have the ETIM classification in the system. The classificationextension is only supported until Hybris 4.8 and ETIM V3.0. Our clients needs V4, V5 and V6. Has anybody experience with these versions on Hybris 6.x ? I can configure it manually but would love to have an impex for this, thus saving a LOT of work.
