This would hurt, and then they’d be a bunch of “headbangers”. 
You can stiil do all these things!
You can modify the tray to meet your needs. You can create multiple trays. You can have some or all trays docked, some or all trays floating, some floating trays on other display monitors, and some docked trays that Autohide and slide out of sight into the window margins.
I have two trays auto-hidden into the left margin, and 4 custom tray tabs in the right-side dock.
See this image of my trays (but then I had the tree and help trays hidden on the right. I afterward moved them to the left side.)
