Mainblocksetchance with ASM

Hello Hyrule Hacking community
My question is asked quickly. It is possible with asm to change the blocksets within a dungeon?
For example. You enter entrance 04, find yourself in the castle. The mainblockset here is 4. Now you go through a staircase and you 're in a cave. The mainblockset is changed to 6. Is it possible to say the game, with asm, it has to load the cave mainblockset if you go through these staircase?

The only thing you can't change when going on a staircase is the wall blockset. Wall blockset is defined at the entrance only. So it is not possible to go from dungeon wall blockset to a cave wall blockset. You can however change the palette and the items blockset, but the wall blockset scrolls through the entire dungeon until you exit.
