I would not do that, 
1. Your tables are locked during mysqldump, So if the table size if too
big then you are without DB at the time of dump on primary. 
2. I guess you will be (have to if the table structure change) deleting
all the tables on the secondary server and then copying the data to the
tables which again takes a while depending on the size of the tables.  
 
Say you setup cron every five minutes then your systems are not in real
time sync after every 5 minutes, in fact they are never in sync, which
might not be a big deal for you. 

Only way to go for this is Setup replication, which takes hardly 30
minutes to do. If you can't do it then pay me $150 I will do it for you
;) Just joking.
