No -- not unless you have a computer radio -- best done through the dual rate switch (so you can enable-dissable the link) the & programmable throw percentages. You will need only a small amount of rudder input to coordinate turns & with a non-programmable Tx the Y will give you a 1:1 ratio of rudder/aileron. That can only be varied by the mechanical set-up of the rudder & aileron linkages -- aside from surviving the set-up flights, if you do that you will greatly reduce rudder effectiveness when you really need it. Additionally, the fixed linking of rudder & ailerons will prevent seperate use of either rudder or aileron that may be necessary in various flight evolutions.

All-in-all a bad idea.
