Thank you for your response.
Although starting from scratch kind of hurts, here I think is not a good option. The site is very well known in its niche, with over 100K customers and 20K regulars, so we are trying to keep the same name (also trademarked, DBA, LLC, etc).
Building a new image for the site and new content isn't the problem, however, I wonder how far Google may take their "penalty-flow" if we start a new Website just using the same name, going from domain.net to domain.com (content and design will be different), but a 301/302 or javascript redirect will be placed in domain.net after all pages are deindexed and there are no traces of the new site.
I must add this is an algorithmic penalty, not a manual. There are no manual actions applied.
