Oh boy...probably a number of different things you could do here...and at least for me, it is sometimes hard to completely envision things without being there. Parallel the two systems would work. Are the 2 direct lines 6"? If they were 8" that would probably be enough to keep things under control by themselves...that's all the T1 even had! Another thing you could do is to put a relay on the main furnace that locks it out when the Tundra blower is running...guess it depends on how much of your heat load you think the TII is going to be able to handle.
I'm sure there are other things you could do too...hopefully someone else will jump in here with a better idea...
