Extend floor joists?


New to the forum. I am in the process of planning a kitchen remodel.

There is a wall that extends out in our eat-in kitchen that I am looking to eliminate.

In order to add the header that would make the ceiling flush from front to back, I would be cutting the floor/ceiling joists and pocketing in a 3.5" x 9.5" header in the ceiling using joist hangers. The span would be ~ 4 feet. I have done this in the past to achieve a smooth ceiling front to back.

The problem is, the joists on the back side of the house are ~6 inches too short.

The joists are 16" on center 2 x 10.

The area above these floor joists doesn't seem to be carrying a lot of weight. Mostly just upstairs floor. No tubs, walls, etc. The area that would require the extending is approx 3 feet. Only 3 joists. If I needed to add 2 or 3 feet on, I would never think to do this, but since I only need 6" total added length, I wanted to ask opinions.

In order to properly extend these joists to the header, can I scab two 2 x 10's overlapping ~4 feet on both sides of each joist, through bolt, and use construction adhesive to reach the hangers? I was thinking of buying the triple hangers. 4.5 inch wide to accept triple joist. I put a picture of one below.

I would fill in the gap in between the 2 boards on each side with a 6" scrap so that a solid, triple joist goes into each hanger.

I could pull down all 11.5 feet of the ceiling and set a new joist on top of the wall, but this would add a ton of work with soffits, bridging and plumbing, etc.

I was also considering adding in bridging in between the extended joists, out onto the un-cut, longer joists on either side for more strength.

In the pic, it you look closely at the top, you can see the overlapped joists and the wall. I want to make that over lapped joist reach the wall.

Any help and advice is very appreciated.
