Virtualizing Remote Desktop serives roles?

Dears,

i am planning for MS Virtual Desktop infrastructure on Hyper-V based on Windows Server 2012 ( 2 servers  with failover cluster)..

i need to install remote desktop roles " RD Connection Broker, RD Licensing, RD Web Access and RD Virtualization Host", the question ,  to save number of servers can i virtualize Remote Desktop services roles on same Hyper-V host which will also host the virtual desktops in same box?

your response is highly appreciated ..

thanks,

Mufleh
