Shade tree mechanics at their best. Your opinion please!

I've got a little problem I could use some experienced opinions on.

My girlfriends truck, Chevy, the heater hose pipe fitting broke off at the intake. The threads are still in the intake manifold.

I know I should just take the intake manifold off and take it to a machine shop to have the thing fixed. However, I am just too broke at the moment and just wanting to try a down and dirty approach.

My first idea is to simply "sleeve" the broken fitting with some 1/2" OD copper tubing. I would either use J.B. Weld or another gasket maker than is waterproof (i.e. liquid resistance to antifreeze.)

My second idea is that if I am going to "sleeve" using the copper tubing, why not just extend it and connect it with a heater hose from the copper tubing to the heater core inlet.
