Framing issue

>First off, my house was built in 1910. I have done some extensive remodeling over the past years.
In my basement (also woodshop) I removed 2 support posts (2 2x8's nailed together) that were NOT original to the house to gain more space in the cellar. The posts were inline with the lally column in the cellar directly under two other posts that were in my kitchen on the 1st floor. Years ago I has a steel I-beam installed in the kitchen to remove the 1st floor posts and figured that the 2x's in the cellar could be removed as well. Now I have a bouncy floor in the kitchen. My idea was to install a doubled up Microllam with two lally colums w/footings on either side burried in the walls of my cellar. Uopn further inspection, the underside of the beam(s) is warped and the beam on the left side is doubled up (4 x 6's on flats). And there wouldn't be room for the duct. My other idea was to temporarily support the floor joists and remove the beam all together, then install the Microllam with joist hangers. But the original joists are 6" apart so I would have to laminate 4 or so beams together.
To describe the picture: The top portion is the "side view". On the left are the 2 4x6 beams which lead over to the column, directly above the column is a "T intersection with another 4x6 that leads over to the main center support beam. On the right is one 4x6 beam with space between the subfloor. The dashes are exagerated but show what I mean by the warping. The lower portin shows the floor joists 2' centers and are staggered from either side ( I was thinking about sistering the floor joists as well, but this eliminated that idea.) Also, the 2 beams are butted together past the lally column. The lower portion is the top view.
