Can the HUD be made bigger?

I created a new shortcut to toggle Bluetooth power. When it happens, I want to HUD to display "Restarting Bluetooth".
However, the current HUD is a small square and the above text doesn't really fit in it, clobbering the HUD box.
It would be nice to define a size for it, or better yet, for the HUD to resize dynamically to accommodate the text in it.
