SBB 4-way pallets

So, I know there are problems with forks puncturing them and causing a mess, but I have an idea that would make them unable to be punctured by a forklift. I have also heard some people say that they let grass grow up into the hive, and my idea might address that to a certain extent as well, so I am wondering if there are any other problems with SBB pallets?

Do they give too much venthilation to hives being transported?

Do they cause problems if a load of bees has to be pressure washed?

Anything else I might not be thinking about that you are?
