The market for Note 10.1 apps has really just started and if this app were to be made for the Note 10.1 it would be an instant best seller.
The Note 10.1 has a stylus with 1024 levels of pressure sensitivity, 2 GB of RAM, a 1.4 GHz Quad Core Processor. So it has a lot to offer in terms of capability to run the app. ((actually it has better stats than the iPad))
Also, as of right now the market for all android drawing apps is still very small in comparison to the amount of Apple App Store apps, so if this were to be made just for android in general, with note 10.1 support and support for Jot Touch (for all Andorid tablets/phones that don't have a stylus included), it would sell very well, not only because of lack of competition, but also because this app is very powerful,well made, and has a beautiful interface.
I know android is a whole different story with coding but I think this would be really good for your company and also the
