and then once you start to get some money you could add a switch. an easy switch for HKK is muay thai(8points of contact) because they have a few stats that go hand in hand. 8pts uses Footwork and speed also, so by training muay thai along with the Kickboxing build you would have 2 styles you could use. HKK/8PTS. but thats just one of the possibilities, there is many more out there if you don't want to go down the road of kickboxing. take a look at the retired fighters on my roster for examples
i train HKK also, i train kickboxing,footwork,speed,focus & power. Some say power is not really needed and some say focus is not really needed. so lately i've been just experimenting with power and no focus. if your on the forums send me a private message and i can help you better. my forum name is RussianThai
are you on the forums, it would probably be easier to help you thru private message. i would start with training one style for you whole camp. looks like you have a pretty decent squad for going HKK(high kick killshot) i would train every fighter for that style until you get more money. its hard to train multiple styles with no equipment.
