It should work, but it would leave you with two dangling ends - one from each whoopiie - and it would give you two buried sections between the end of the hammock and the tree strap, so you'd need to have trees farther apart. Using a fixed loop on the hammock side you can larkshead onto the hammock, and even run the buried part around the hammock more than once so the hammock to tree strap distance can be shorter. I think you can cinch down a larkshead pretty easily, even a double wrapped one, and it's not a connection that you'd undo unless you wanted to re-gather the hammock end.
HamMike's right. It will hold. By the way, "Larkshead" and "Girth Hitch": same beastie.
