Can I use UnderQuilt Protector as a hammock for my daughter?

[AVatorL]

While I'm waiting for my 2QZQ Argon 90 Underquilt Protector to be delivered I got a question. It will be my first UQP. I'll use it in some cold/windy/rainy weather. What if I the weather is good and I don't need it as a UQP. Do you think I can use it as hammock for my about 5 years old daughter? I'm thinking about using lark's head knots on the ends when I'll need to use it as a hammock, so I don't need to make any permanent changes.

By design it's just a same rectangular piece of fabric with sewn channels + a piece of shock cord, right? It's shorter than a regular hammock and the fabric is not strong enough for an adult, but it should work well for a child, isn't it? Or am I missing something important?
