With the group you want you can set up a 7 hit combo that can start with any one of them. just put gaara and neji in front of one row each, with kakashi and main behind them. as summon use ninja dogs or if you got lucky a high combo summon or white snake. its a damage group with no healing

k G x
M x N
x x x

with talents set to 23311

would be a good setup

no swap kakashi and neji.

like this.
kakashi gaara blank
main neji blank Enemy Team here
blank blank blank

yep. here is a link to the combo simulator http://*.qq.com/tool/huoying/mnq.htm its in Chinese but you can compare your ninja and summons to see what works.
