Most gathered end hammocks allow the sleeper to sleep asym - even ones without a footbox like the Blackbird has. Wilderness logics has a drawstring to make a foot box - some folks have those installed on all 4 corners too. Other vendors have that too.
You might also want to attend a group hang and hope to try a JRB bridge or a Warbonnet Ridgerunner for side-sleeping.
"Climb the mountains and get their good tidings.
Nature's peace will flow into you as sunshine flows into trees.
The winds will blow their own freshness into you, and the storms their energy,
while cares will drop away from you like the leaves of Autumn."
— John Muir
