I used to ride 27" on the rear and 700c front and it felt superb. I realise the difference here is bigger, but you never know. Dependent on the frameset it may work out ok. The question however is why? If you already have the 650c but no front 700c to try, then experiment with the 650c by all means. But otherwise it seems silly.
