In many European countries, leaving academia for a job in industry will make it hard to go back in case you don't like the new job. I'm a tenured full (CS) professor in Germany with some excursions to industry (research) and had to struggle quite a bit (and have a lot of luck) to be hired in my current position.

Maybe there are some alternatives you could try? Many universities offer the opportunity of a leave of absence for a year (or possibly more), so you could try out something else without having to fear losing your job - of course, your publication and funding record will still suffer, but this is maybe not so critical since you already have tenure.

Another idea might be to use some of the ideas from your research and try to commercialize them in a startup - perhaps together with some of your students? If this works well, you could also apply for a reduction of your position at the university to spend more time at the startup.

Also, applying for a position at a different university (possibly in a different country) might be an idea? Of course, this might be a less attractive option considering you just bought a house.
