Always On Availability Groups

Hi

I am investigating Always on availability groups in our SQL environment

I would like to create two availability groups,

group 1 containing db1, db2, db3, db4 from a primary replica on sql instance sql1 going to sql instance sql2

group 2 containing db5, db6, db7, db8, db9 from a primary replica on sql instance sql3, can I have this group also going to sql2?

the databases on sql1 and sql3 have high batch transaction loads, and I need to keep them separate, but I would like to use sql3 for read only reporting

I would like to hear peoples options

thanks
