Hey man i like ur plan it has alot of good spots in it.But personally i feel ur being a tad too ambitious with it ,ur pretty much spending lot of time traveling which is something i 'd hate,Plus ur travelin in such a big group it could be abit taxing while doing so.Just my 2cents i think its very reasonable to do Tokyo + Kyoto + Osaka within ur time,even still transport is still gonna be costly.u could hit himeji when ur staying in kyoto/osaka its not that that far.Doable.
hope this helps=).Kobe isn't a must go now because its not nicely decorated like it always is during december.Nara is a nice place for the family especially for the kids(deer feeding)
