I repair lots of displays by replacing glass and tried an S6 edge yesterday.
To be honest I will be Very suprised if it can be done the touch digitizer is glued to the glass using a Very Thin oca Sheet that needs to be warmed up much more than the other models it is also longer than the lcd itself as it goes right over the soft buttons.
Heating the glass up enough to make the glue soft enough to separate it needs around 80degrees
I have found that the digitizer then separates from the lcd completly making the display unusable.
The lcd underneath is quite flexabile also making it even more tricky.
I Hope I am proven wrong but it is completly different to the other more rigid models making them more easier.
