Why are you making such a big deal about Raspberry Pi wallets? It is hardly anything special apart from it being nice to stake at 5W. Iv been making Pi wallets for tons of other coins and posting them in the respective threads for free in 99% of the cases. Most of those coins have died down in anyways because wallets for a another platform is not a competitive advantage but a commodity. From experience in the repo download history I can tell you that there are max 10 users interested in Pi for a coin and apart from those users it is but a hype factor that speculators use to hype the price of a coin to dump on the back of it. In addition Gorillastake.com for example has been hosting online Pi staking solutions for a long time. Having said this, good luck and it is a nice thing for those 10 odd users and I hope it makes a difference in your case.
You should come up with something special to promote your coin. Devs are not doing other real special things that drive the success of a coin and wallets for other OSes are not it, including mobile wallets
