Thinking about this miner again and again but im not sure about it as current miners are also not that much efficient to have profits over the long period of time. I accept that you have modified the miner with all the goodness of nvidia chips but do they really have benefit. How much electricity consumption and have you done any mods in that part. That would be really beneficial if you do. 
Thank you for your question!
It is pleasure to make conversation with you!
We are already reached more efficient results compared to graphic cards mining.
Especially in power consumption.
When we get more resources for research, we will continue more advanced improvement of this technology.
Maybe, if it still be an interesting for us - we will make something new.
We have already developed some improvements to those models. If we can realise them, we will publish some News about it on the web site.
