There's no point wiping until you fix the issues you've noted in your internal discussions as being the need for the wipe. The wipe itself will just delay them re-occuring, not fix them.
I would accept a wipe, but there needs to be a recognition of the effort current players put in, based on your committment to not wiping. Converting quanta \ assets into gametime perhaps?
I'd also like to see creative stuff retained, voxel only blueprinters for example.
If it's just a hard wipe, I wouldn't start from zero again.
