To answer your questions, NO and NO.
The early season was put in to accomplish early doe reduction in line with the goals of AR. The chance that they will allow Buck harvest then is slim and none. As far as allowing modern muzzleloading in late season, and I asked this question of the headquarters in Harrisburg, is NO. They told me that there is no suggestion of this in the forseeable future and the fella told me that if I want to use a modern ML then I should use it in the regular rifle season, as flintlock STAYS flintlock, PERIOD! I then went out and bought a flintlock, Hahaha..
