I think making a decent tent would be hard work - the materials are available - but seaming and joining in a strong and waterproof fashion looks troublesome - for example Hilleberg use special machines that cool the needles so the material doesnt melt.
How about a tarp though - with a couple of walking poles, eyelets in the corners and some lightweight line, that could work well.
Otherwise a decent little-used tent is a better bet.
