Good question!!!
Australian answer..
A missed approach must be executed under only certain conditions which this is not one. However, unless within 1/2 scale deflection descent must not take place. If you go outside 5 degrees of the inbound track then your LSALT is at risk and you need to climb to MSA. An ILS is only 2& 1/2 degrees. I would suggest if you go to full scale climb to at least MSA until you regain track and then try to get down again!!! No more than 1000ft /min.....
