Brad, I would worry that the stick would poke through the fabric. I do similar with my tarp to hold up the middle, using a hiking staff. However, this is around a 1″ diameter staff (actually it is my wife’s staff.) You could do this from the outside with a sticky patch and a loop. After the patch has dried, you can use a found stick to hold it up and stake it out. Don’t worry about left and right pressure, it seems OK with a single staking point.
Next would be to simply use your pack. You are quite tall, so this may not be an option.
The other thing of a more minor concern, is the change in geometry, due to the lifted corner. DCF does not stretch easily, so, any support would likely change the entire geometry of the tent. You have a little to play with, but not much. It could make the door come loose at the bottom or create a puddle or wrinkle in the canopy if it is too high. A 3″ or 4″ lift will likely not effect things, though. The end will want a small triangular piece sewn in, similar to other Tarptent models, to compensate for the geometry change with more lift.
