much can be said about the strength of concrete One of the primary points is that it essentially has zero tensile strength. If the center of gravity gets in-front of or behind the base plate you run into a situation where concrete, somewhere, is under tension. The extended base plate does not need to be thick, all the strength should be through the gussets. For example you could have a plate as thin as 1/4" but 3 feet long and as wide as the base plate and a gusset consisting of 3" or 4" square thick wall tubing cut at 45's and about 1.5' long welded professionally to the post and the plate.
I am 6 credits away from a BS in mechanical engineering from Penn State and none of those 6 credits deal with strengths of materials. This is merely advice, I suggest that a certified engineer signs off on any modificationss.
