Advice on hybrid setup ( office 365 + on premesis )

Hi,

Presently we are using office 365 E2 enterprise edition in our environment

we would like to add an on-premises setup (exchange 2010 or exchange 2013)
in our organization which uses the same "abc.com" domain.

Main motto is, for users who need to access to all the features like lync,sharepoint sites etc. and large mailboxe size would be  given accounts on office 365 server ,remaining will get accounts on the on-premise exchange server. 

Hybrid setup with exchange 2010 would also be fine ,if hybrid setup with 2013 is not supported.

Any one have any advice on what would be the best setup?

Thank you.
