We realize it as well, Theo. It's expected, and your friends expect such self-awareness.
And, uhh...
It just doesn't seem necessary to me to make any changes to Peach or Jigglypuff.
This goes especially for Jigglypuff, who, IMO, can be argued for the #1 position on the NTSC tier list (along with four other characters).
Peach, if anything, could be made a little better, though I fear that even minor tweaks can tip a character out of balance.... So, I don't think that I have the wisdom to describe what specifically needs changing. Perhaps making U-air and D-air more combo-friendly, but increasing the knockback of another fast option to compensate for removing a kill move.
Peach needs a better way to maneuver herself around the stage. Either faster ground speed or perhaps make her jump speed higher and allow her to pressure top platforms more easily. The problem with peach is that she is zoned way too easily. She's good because she has really fast moves that are strong and stay out for a while. The problem is she is slow and has no range. Fox/Marth/Sheik can just run away and defensively space way too easily against her and just swat her out of the air as she is desperately chasing you or just shoot lasers/needles. Peach is good when people don't play gay and run into her moves.
I also think that some of peach's gay characteristics should be changed too. Make downsmash not as stupid (not broken, just stupid) and take out death radishes.
