No. No. No. No. No

Nylon strings will not work. The neck is set to handle metal strings which have much, much higher tension than nylong strings. The neck will bow back, maybe twist if you do this.

My advice is to keep going and you will get better. Trust me, your fingers will adapt.

My "cheater" way of handling this is to put a capo on the first or second fret and retune the guitar accordingly until your fingers get stronger.
