Hi Francisco, I'd be inclined to take all the branches right back to the main trunk. That's the usual process for pollarding. For mature trees this shouldn't be a problem. It's common where people have large trees in a small garden and want to keep the tree, or in an awkward site - for instance, where the tree may cause a lot of shade.
Others may have a different opinion
