Buvagen back to A

Hi!

I want to know if there is a passage for two experienced people ready for some wild days to hike from Buvagen back to A or Moskenes?

While checking maps and satellite-images I think about the route like this:
1.) boat to buvagen beach
2.) going up to Hellsegga
3.) going to Turtnbakkvika either along the coast or along the mountain via Sortinden
4.) going to the beach Gjerdvika
5.) passing to Agvatnet
6.) back to A

I'm really unsure about the ridge to Sortinden. It looks manageable, when there is no ice and snow actually.
