I think the reason JWs don't use Hebrews 2:5 is because of its proximity to Hebrews 2:7,8.
Hebrews 2:7-8 — You made him a little lower than angels; with glory and honor you crowned him, and appointed him over the works of your hands. All things you subjected under his feet.” For in that he subjected all things to him [God] left nothing that is not subject to him. Now, though, we do not yet see all things in subjection to him;
It wasn't subjected to people. Nor was it subjected to angels. It was subjected to a human who became a spirit, whom the angels themselves worship. (Hebrews 1:6) It will be given to the meek and righteous when they become spirits, as well.
There will be a resurrection of the righteous and the unrighteous. I encourage anyone interested in the resurrection to life to consider the usage of the Greek word "zoe" (Strong's g2222) throughout the NT. (Narkissos, that is a Greek word, right? )
I have selected some verses that use it, and highlighted where they appear. It paints an interesting picture when compared with WTS dogma.

Thought to ponder on Revelation 2:7 — Did the congregation in Ephesus have an earthly resurrection to look forward to?
