I don't think I would want to trust the kickstand with the extra weight and force of my wife climbing on.
She's not that big...but those bolts have been known to let go and I'd hate to bruise the bike!
Even with a 31" inseam, I'm long legged enough that I can squeeze and balance the bike between my legs and hold the front brake as she climbs on or off.
She steps onto the foot rest and swings her leg over the seat, thru to gap.
