That plan sounds valid.
BTW, it's not an official "overflow", it's that two tubes fit together without any seal, the part you see under the hood, and the tube from the reservoir.
The reservoir is know to have a leakage problem caused by a stress point at the bottom tank mount.
The repair is to reinforce with a proper sized steel washer and JB Weld the heck out of everything there.
Worked for me 5 years ago, still not leaking.
