I live in an antique home with 2×6 ceiling joists. The stairs are being rebuilt and the current hanger board for the stringers will not work. So I have attached a picture of the current setup and one of my idea to extend the joist down using a 2×12 and strong ties securing it to two adjacent 4×4 posts. Please let me know your thoughts on the strength of this design. Or any improvements or different ways to extend it down.
There is only about 2 inches behind the joist and posts to accommodate anything do to a finished room and basement stairway. This is why I've taken a minimalist approach.

I am going to assume the opening for the stairs is on the far side of the picture.
I'd skip the ties and use 2x12 hangers on the posts. If you have this area open you might want to tie the 2x6 joists to the 4x4 posts using ties for seismic/wind though.
Why does the current board not work?
