Can I replace two 2x4 jack studs with a steel bracket attached to side of adjacent 6x6 king stud?

As part of my kitchen remodel, I want to move my refrigerator into a closet. In order for the refrigerator to fit width-wise, I need to remove two jack studs on one side of the closet that are supporting a double 2×12 header which is a bearing wall for the ceiling joists and second floor bedroom.

The header butts up against a 6×6 king stud that the jack studs are nailed to.

My question is:

• Can I fabricate a steel bracket lag-bolted to the side of the king stud to support the header instead of the studs?

• Would I need to extend such a bracket down the side of the 6×6 and attach it to a steel plate at the foot so the weight remains supported on the floor rather than hanging on the side?

• How thick should steel plate be?

(Note in the pictures there is a third stud which I removed, shown in the location where I pulled it from. The bracket would replace this stud as well)

Removing the studs frees up the three-inch space to the right of the 6×6 post
