I recently downloaded a mod that lets me craft a ''grenade" type item that lets me basically summon a set of Power Armor to me. Haven't ~tried~ it yet, but in the comments for the mod, several good ideas came out, most of which will have to wait for formal tools to become available.
The best combination of ideas I saw suggested was the ability to summon a ~particular~ set of power armor and have it be air-dropped down to your position (hopefully far enough away you do not take Impact damage when it lands!). Some even suggest having a Vertibird fly in from out of sight-range and then have the armor drop down from the Vertibird, landing with a KA-BOOM nearby. Others suggest having a dummy AI NPC inside the armor use the jet pack to fly from out-of-sight into visual range and ~then~ drop down to the ground.
There was also talk of having a Power Armor ~pickup~ or ~send home~ feature where, for example, you could get out of the power armor and then send it "home" (to any settlement you select, to a pre-designated power armor station would be great) and it would then (with a dummy AI NPC spawned inside) use the jet pack to fly out of line of sight before despawning and respawning at the settlement in question.
