Replacing floor joist

I have an old 2 story home. Iside dimensions of the basement are, 22x30. I have 6 inches from the top of the stone/concrete foundation to the bottom of the floor. Their is a 6 inch timber on top of the foundation, leaving about 12 inches of shelf at the top of the wall. All of the floor joist are unfinshed timbers and need to be repalced. They are about 3 feet on center. I had the following ideas but not sure which to use.

1) Use 4 2x6x16 for each joist to make a 4x6x22 joist and place 12 inches on center.

2) Use 2x12's to make the floor joist and notch each end to fit on the foundation wall and secure to the perimiter timbers.

Either way I expect I will need to run something down the center for support. I am leaning toward plan 1 with a 2x12x30 down the center supported every so often by a floor jack.

Any suggestions or comments. I am open to a totaly diffrent idea also.

Thank you.
