[Suggestion] Explorable versions of key story instances

It has been trend lately to introduce important Guild Wars 1 landmarks into story instances. The two most recent ones are Fahranur and Gandara. Although revisiting them during key moments of GW2 feels right, it is a shame that those iconic places remain inaccesible outside of those story instances. I, for one, would love to be able to walk into an open-world version of those two iconic places without having to go through dialogues and tasks that I have already done. What is the point of clearing those places of corruption if there is no follow-up ?

Claw island would be neat to go back to also..or well..any unique to the story area ;-;

For gandara can we have that stupid sewer grate opened so we can explore the inside again, would be neat.

When I read "explorable" here it made me think of the old "explorable mode" dungeons, which could also be a good use of old story instances. I suggested this in another thread, but creating new PvE scenarios that use old, unused maps is a great way to both reuse those maps and introduce some more group PvE content outside of fractals.
