Now let me quickly throw this out before I go on, I have never used a Warbonnet, never even saw one in person. But just from seeing how you want simplicity I think the Hennessy is an easier solution than what you are describing here....and cheaper.
The Hennessy may look complicated to set up in pictures...but is in fact extremely easy. AND when it is up there is a bug net in place. No hassling with sinkers or anything. The tarp is also extremely easy to set up....two already made prussic knots on the ridgeline to connect the tarp too, stake the guy lines, and WALLA!
Just my 2 cents.
