Samurai Lego Bricks?

[Threule]

I'm not quite sure if they are some sort of do-able, but I'll just leave my requests here:

From this set, I think the banners and the grey walls could be done. Not sure about the fishies.
Maybe the doors too, we could have more Lego Door stuff in the game.

The banners could be substituted with a 2x2 print on RTB.
The doors are achievable with JVS on RTB.
Everything else is already made.
Just get these Add-Ons and you can make this.

I dont see these gray rock walls anywhere, with the decal and so.
