There’s no possibility to recover stuff on your own and I’m not sure if the developers could help.
BUT if you decide to start over you could basically count on the community to help you out with a set of tools to progress a bit faster.
Actually that’s something that happens every now and then due to people which stopped playing before the reclaim system was added. Back then when people’s beacon fuel ran out they lost all the content of those plots. By now if your fuel runs out you can reclaim all that content in a new beacon of the same character.
Some of those old players return every now and then and get help as well if they ask for it
