You should check out Beebop's Chance Hardman Adventures.
This link is for a few single offline missions.

In terms of your get out run around and adventure , this is really beyond the IL2 engine , what it was
designed for , and how most pilots use it.
From my thin knowledge of modding and modders , it would take a lucky strike for you to reach a modder
willing to even contemplate going there , but hey this is your concept and no dreams means no development.
Good luck.
I want to steer back to your original idea for this thread ( chocking/anchor mechanism for seaplanes )
because :
1) I believe it to be quite doable in the technical sense
2) I believe it would enhance seaplane missions to an enormous degree
3) I bet there is a modder out there who will be curious enough to tinker with
the concept.
Thanks for voicing this concept , Strawkalling.
