It is possible, but there are few things which you need to have in mind before doing anything. First you need to be aware that at the moment transaction fees are too high, and i would not recommend moving your founds unless you really needs to. Also i am not sure if there will be fees on Yobit, but i guess you will need to pay them some part too. In general i would not suggest transferring anything, anywhere at the moment... at least till fees go back to normal.
For sure you are right know its extremely huge in Xapo you have to pay about .005 btc to send your payouts out and I won't do that at the moment but when transfer from freebitco to yobit they only take a withdraw fees 3000 satoshi and deposit in yobit is free
