This is something I do when I'm learning something that I find difficult as the classical position is definitely easier to play, 99% of my playing time though is spent with a guitar on my right leg (I'm right handed) just because it is more natural and comfortable to me. It makes my Uncle cross when he sees me playing the lovely classical guitar he gave me not in the classical position it would probably make him cry if he knew I use a plectrum on it quite often! (classical guitar is great for practising stuff without the pain of steel strings!)200 years of classical guitarists say it goes on left thigh. I've noticed lots of electric players go with the right. Dunno why that is.
Give it a try- and get your left foot raised on a box or similar.
