Yes ,it's possible (installing sp1 is recommanded here )
now the question is , will you have two differents sites ? or both servers will be in the same place .
if you need a site resilience and disaster recovery there's some considération to take . if not
simply build your DAG and dont forget to set the alternatif witness server ,and set the DAC mode to DagOnly .

Just so you know, you need Windows Enterprise version because a DAG requires some clustering components.

Our existing Exchange server is installed in a 2008 R2 standard server, under Hyper-V environment.
Is it possible to upgrade the 2008 server from Standard to Enterprise directly? Without affect existing settings.
