I have an idea for a three quilt 4 season system and was wondering if anyone has tried this yet.
What I would like to do is buy or make a light weight TQ/UQ combo for warmer weather.
But I would like the ability to convert the TQ to a UQ and add it to the other UQ "stacking" them to be used with a heaver top quilt essentially creating a system of three quilts that can be used in a wide range of temps.

Living in Alabama I would very rarely see temps that get into the teens so I'm thinking a 20deg TQ and the combo would be 2 40 deg quilts.

Does anyone see any flaws in this system?
