Overkill to the nth degree. Like using howitzers to kill mosquitoes. See my response under your original thread.
But should you insist on making the living room floor strong enough to launch Saturn rockets from, don't forget to use full-penetration, single bevel groove welds for all column to plate welds, using E7018 electrodes and proper preheat. Ordinary fillet welds will not perform properly. Might want to have the welds radiographed as well, to catch and correct any hidden flaws. And of course, only High Performance Concrete will do for the infill, with a compressive strength of at least 10,000 psi.
OK, sorry for the sarcasm (but not really). What I and nealtw are getting at is that you are making more work for yourself for no logical reason. Totally unnecessary.
