Hi Tushar,
(I'm assuming you're asking if that's a good idea or if its possible to do that)
Some very simplified BW scenarios can surely be ported to Suite on HANA.
BW scenarios with stronger complexity (harmonization between many system types and layers) will definitely require a thorough project in order to analyze the impact or such change.
However, I think the first question is: why do you need to 'get rid' of BW?
I suggest you to start off reading SAP HANA Live versus SAP BW (powered by HANA): When to choose what?
As well as https://blogs.saphana.com/2015/07/06/sap-hana-replace-bw-hint-no/.
