Regarding whether or not this would change the staff's current recruiting goals for O-linemen: only if they were thinking of getting five in this class to continue to make up for the small Lombard class. Typical goals for O-Lines are four per year, or sixteen on a roster. The O-line allows a bit more flexibility than some positions because the players often have inherent flexibility to shift positions, and coaching staffs like to really emphasize the Iron-Five fingers of the Mailed Fist in games [which is why we see less substituting there in real games]. That said, and taking into account the staff's attempt to heal the 2010 gap with shifting Heggie and considering Hounshell as an O-line possibility, I'll bet that they have breathed a sigh of relief and settled happily on a target of a "normal" four. If more super-studs suddenly wanted in, and other areas were "OK", then sure, we'd take five ... but I'll bet no way we want to stop at three.
