When you say in conjunction, what do you mean? If you have a separate Aruba System at one site and a Separate Alcatel System at Another site, they can both be managed with Airwave for monitoring, yes. What you should not do is attempt to have Aruba APs connecting to Alcatel Switches or vice versa; The licensing is different, the code is different, what APs use to discover controllers is different, as well. Lastly, TAC will not support a mixed deployment like that. It is best to contact your local Aruba Sales team for the best way forward.
