I think a slight reality check on what quality of life 'is' for the European pilots working for a TP operator. It usually involves cr#p pay and conditions, working up to the maximum hours each month and almost all your colleagues trying any way they can to leave. This is not to say that there are no happy TP pilots, those I flew with in Scotland doing Highlands and Islands loved it because they could live in their location of choice. That seems to be the only 'quality of life' card that carries any weight. Oh, and most of them were also drawing a pension from a previous life, that helped.
DIRK85 should analyse what particular items about his current job make him the least happy (because, lets face it, pilots by nature are always unhappy about something!) and make damn sure that particular issue is addressed by moving to a TP. If its not about location,location,location, then the golden glow of a new job will soon wear thin.
And, another type rating on your licence, in this day and age, carries absolutely no worth at all, unless you happen to have a matched pair of A320 and B737. Even then, without a regular LPC, one will be useless after 2 years.
Keep with the jet time and hope for happier days,IMHO.
