I’m of the same opinion. The entire Yankee line would’ve easily folded with a bold attack on Cemetary Hill, especially after heavy over 100 miles of marching for the past 5 days in the heat.
I’m also of the opinion that Lee should’ve withdrawn after the 1st further South to feint a direct assault on DC considering the failure to take that hill.
Or at least consolidated on and dug into Seminary Ridge and forced Mead to attack him. (Meade admitted later that he would have done so.) This is the course of action Edward Porter Alexander thinks they should have done. Lee's excuses for not doing so are unpersuasive.
