I am planning to walk a long distance path, and want to carry as little as possible (both in size and weight). I normally take a sleeping bag with me, but as they are somewhat bulky (size matters more in this case than weight) I am looking for an alternative.
Sleeping bag liners are very compact though not particularly warm. I started wondering if it would be doable to use more than one sleeping bag liner (either silk+silk, or silk+cotton, or cotton+microfibre, or any other combination). I don't need a lot of heat (and can always sleep with some clothes on if necessary), but would need a little more warmth than a single liner provides.
Does anyone have any experience with this? Is the difference noticeable? Is this just an absolutely crazy idea?
I think your idea is crazy.
Silk+fleece would be doable with night temps above 10 C.
2 Silk liners would be ok with night temps above 18 C.
Forget about the rest of the combinations.
If I was you I would shell out for super-light weight summer sleeping bag (200+ EUR, Yeti or Western Mountaineering) or sew my own very lightweight down blanket. Sewing your own down blanket will cost you around 100 EUR if you got a sewing machine at your disposal. There are a bunch of instructions online on how to do this.

well said t_maia!
If you don't sleep well, you won't walk well. Look after yourself and go for the best, lightest, warmest sleeping bag you can afford.
One more thing: protection from wind chill and rain is are actually far more important than the actual warmth. You do not sound as if you are planning to take a tent, so how are you going to stay out of the wind and rain? The normal solution would be a bivy bag.
Depends on when and where you are going.
We were in Turkey, Syria, Jordan in mid august when the day temperature is above 40, however, it still gets chilly at night, and you feel cold with 2 layers of fleece and a thermorest mat.
