You don't get into trouble for relisting items no matter how often you do it - all that happens is that if you run out of "free" listings, you end up paying.
However, that's not a good idea as it takes anywhere for 24 hours to 30 days for listings to populate in external search engines. If you're constantly relisting, you lose that.
You can just let the listings relist every 30 days, but decide after one or two cycles to tweak the listing and then create an entire new listing.
