Let's say an all time boxing great like tyson or toney fought against pro kickboxers like ernesto hoost or badr hari, who wins?
The one that learns some takedowns and submissions.
Let's just say they both want to stay standing.
Possibly the kickboxer due to using low kicks and creating space with the kicks so the boxer cant come in and devastate....if a boxer gets inside then its a win, outside its a win for a kickboxer
Very few K1 guys chins hold up, really depends on the guy. A guy like Mark Hunt would probably have a better chance in a standup MMA fight with a guy like Wlad then Badr would because if Badr takes one flush punch he is most likely done.
The kick boxer 9/10 times
Probably look like Bonjasky vs Mercer.
Never seen that fight, thanks upkick
K1 guy is at a big advantage. The stance translates more to mma than boxing so theoretically, they will be in better position to attempt/ defend a takedown if it came to that. In the standup portion the kickboxer has a significant advantage at long range (kicks) and short range (clinch/ knees). The kickboxer has many more options and would make it very hard on the boxer. 
LOL@ Putting Tyson against a k-1 guy,
The first elbow, knee, or kick that landed would send Tyson into a Rage of Zombie like flesh eating for being a "dirty fighter"

This.
8 weapons > 2 weapons

Kickboxers would win. They know 2 ranges and you have to constantly switch between the two.
Boxers only know one and can't defend leg kicks. Destroy the legs and boxers don't have their slickness anymore.
Kickboxer 7-8 times out of ten.

An elite kickboxers leg kick will nullify an elite boxers jab. Kicckboxer should win due to having more weapons
Styles make fights. Depends on who the fighters are. I think a prime Tyson or Holyfield could probably put a hurt on some top K1 guys, but would falter against others.
K-1 HW fights are pretty sloppy. If a bomber of a HW were to fight one of these guys standup only, it would be nasty, brutal and short in favor of the boxer. The inability to avoid punches would be more detrimental than the inability to check leg kicks. Wlad and Haye all day over the K-1 crew
