CI + HMVC + Datamapper + (optional HTML5 boilerplate)

[eluser]Unknown[/eluser]
Hi guys,
I am new to CI have read much about it. Also I have tested many other frameworks like yii, zend and many others. Out of those I liked CI. So have decided to use CI for my next web application. I checked many blogs, forums and tutorials and found that CI is best when used with couple of libraries/framework. Hence decided to do something like
CI + HMVC + Datamapper (I tried to used doctrine but it is very complex to use). Also I am planning to use HTML 5 Boilerplate but some how I think it is clashing with HMVC.

I would be grateful if I can get any reviews / suggestion of the above proposed framework and also like to know if I can use HTML 5 boilerplate with above three without any problem,

Any help would be greatly appreciated.

Regards,

Chintan
