Extending network over a dry pair

You don't even need LOS to move more than 1.5 megabit/s over wireless. 

I think the best bet is to consult people that actually know wireless.

If this is telco provided dry pair then the distance is probably longer 
than 6 miles as the endpoints are probably tied together through a telco 
CO. 

I have not heard of any equipment which will work over a 6 mile pair any 
faster than you're getting with T1. 

You might consider setting up wireless repeaters to bridge where there is 
no direct LOS. Look at what the hamwan guys have done. http://hamwan.org/
