Okay. I've looked at the diagrams a few times already. I didn't understand that the two hoses going into the firewall and then the Heater Core were both supply lines. If I were to do a bypass, my guess would be that I cut the 2 tubes going into the firewall, put an adapter on the remaining hoses with a horseshoe U-tube. Then I find the exit/Return hose and clamp that off. This would cut the supply and it circles back into the Radiator and when it (the anti-freeze/water) tries to collect from the exit/Return from the Heater Core...it doesn't know where to go because it's clamped off so it to then circles back to the Radiator.

Is this correct?

This will temporarily still cause extra work on the engine and it will run a little hotter and I'll have no heat; however, it will work temporarily and I can get the thing up and running assuming nothing else is wrong. And there shouldn't be anything else as it sounded pretty good the last few times I've run it before the Radiator remove and replace.

Update: I've seen schematics of the whole VAC system but I don't see where the return hose comes out of the firewall.

Thanks everybody for the exceptional advice / input, etc.
