Removing Lally Column opinion

House is a ranch, truss roof. engineered floor joists on 16" ctr. meet over double 1 3/4 X 9 1/2" LVLs in semi finished lower level. LVL girder is recessed into pored foundation at one end, a lally 7' (at C/L of girder) away, and the end support along girder is 4X4 with girder butting up to basement stair raisers, 14.4Ft total length. Floor Joists are 20' long with the south joists supported 12' from girder by a 2X4 partition/barring wall separating finished family room from workshop. North joist supports kitchen/ dining room floor above. I wish to sister 2 more LVLs, same as original,to the existing LVLs inserting the one end into foundation wall, as it was poured to receive them. Notch in wall is big enough now. I will remove the lally and move it to the stair wall end of the girder and build a double top plate 2X6 knee wall out 3 feet from the end to spread the load. I will sister the new LVLs with glue and bolts as recommended. Temporary supports will be installed until project is completed.
Any comments? Loading looks OK on paper and the added bearing support from the 2"X6"X3' should eliminate the cement basement floor loading problem, but would like opinions.
