Well my wife's first bike was a 07 883L The L = lowered which was good for her and she is 5'7". I suspect that you would need at least that, and maybe even some good boots. Are they top heavy? Sure, maybe a little but nothing I think worth debating. The other big twin bikes you meantioned are going to be heavier regardless of where that weight is. The only thing worth considering IMO is that the sporties are a bit wound up on the highway, more so the 883 over the 1200 which she has now.
Her 07 883L
her new 1200N (nightster which is also lowered).
Dont mind her cheesy smilie, that was her first day riding solo on her new bike, rode it to work n back.
You can see how well her knees are bent at her 5'7" hieght, so at 5' even you will probably be on the balls of your feet.
