I wonder if the wee pea tendrils will attach to the mesh? If you pull the mesh a bit in opposite directions the mesh opens up a bit (Only found this out on the weekend trying to attach some to the fence with wire ties), so maybe if you did this at a few points along width at different heights it would have a dual purpose - wind break & frame. Not a hassle at end of season, let them dry off & brush them off the mesh & use for years to come.
Tiger - creative as well & could well work! Good you've got the height in the greenhouse to grow sweetcorn. My 2 that germinated are going in the back garden to be molly coddled into maybe 4 cobs!
