yes, kamailio can be used as frontend and should be no problem 
implementing what you need.

As a remark, if you forward REGISTER requests, you should use PATH (see 
path module) in case you need that requests pass through kamailio. This 
requires that the registrar supports PATH extension as well. For dialog 
requests, you should use record_route().

A starting point could be the example from dispatcher module is quite 
close to what you need, see:
- http://kamailio.org/docs/modules/stable/modules/dispatcher.html#idp1885888

You would need to decide how to select the dispatcher group (set) id for 
routing. That could be done using mtree if you select the next hop based 
on a number (e.g., dialed number). If it is alpha-numeric based 
selection, maybe htable or dialplan are good options.
