Just gathering thoughts for how this might work, watch OS 4 has some extra options which might make it possible in a convoluted way. This is truly NOT an AW on android, but it should work as a companion to an android device in many ways.
So my thoughts are to get a cheapie 5s ($79) and just leave it at home, connected via wifi. This would connect to the AW and from what I understand in watch OS4 the AW will now connect to wifi networks on its own, even if not in proximity of the iPhone. Yes that means it only works on wifi, although I would assume that means hotspot as well, so the AW should connect to the android phone via hotspot so it can get information from the iPhone at home and stay connected.
Email: Simple, just setup the cheapie iPhone with my email account. I should get alerts on my AW via wifi, as well as on my Android phone.
Text: Most of my texting and calls are done through Google voice, so I just have to set it up with both the crappy iPhone and android phone, should come through wifi.
Calls: I don't think this will work, although it's possible that incoming GV calls might show an alert via wifi, not sure.
imessage: The only solution I could think of is if I had people message my email, then the iPhone should get it and transfer it back to the AW. I can text from the AW and I'm assuming it would come from email, not sure.
Motifit/fitness/heartrate: Seems to work standalone with the AW, can sync it when I get home.
Apple pay: Works right from the AW without the iPhone having to be in proximity after initial setup.
Calendar: Just setup on iPhone, reminders should work.
Siri: I believe some limited functionality is present on the AW by itself.
What do you guys think? I'm just kind of brainstorming here. I really can't stand any android watch and don't think I can deal being without my AW.
