So now what - more alternative endings

So now, for those of you who are still reading (if that is anyone) we come to the vexed question of endings. I am now faced with a number of options which could challenge the Orpheus / Eurydice myth - Adonis knows what has happened, and that it breaks the rules for gods / goddesses so he knows he can do something about it... but what does he do, and what is the result ? There are a number of possibilities - and I'm torn between them - one of them is right for the story, but I don't know whether I'm allowed to rewrite the myth's ending - where Orpheus and Eurydice are reunited in the underworld after his death.
That ending is a possibility in this story too- either Adonis bottles it, or gets stitched up by the immortals, or they decide the rules haven't been broken, or Eurydice decides to stay down there, whatever - whole range of possible ways of getting to that point ...and that might keep the myth with it's traditional ending - Orpheus dies / is killed whatever - and ends up with Eurydice down there - and they remember each other in spite of what I said earlier about memory and time and death.....but is that a happy ending ? Not sure if it is, or if that's how I want the story to end....onr option could be that even though Eurydice is allowed to go back up, Orpheus has just been killed and she decides to stay so they can be together...ahh! true love rediscovered....

The alternative is to drop the myth's ending entirely and have Eurydice escape - be allowed back up - because of the plot by the immortals - and she then decides whether she finds and gets back together with Orpheus and changes his mythical ending too - or whether she runs off with Tony (Adonis) or whether she does neither and settles for a new life without either of them....

There are far too many options and I need some help to decide - am I a myth-buster or do I go along with it....could do either - still haven't done the guide book or the bereavement counselling manual yet either....what am I like...
