A large capacity tank has to be a plus, but are you trying a play on words with "leak-resistance"? Actual meaning "able to resist leaking of liquid to some degree but not entirely" . Assume that's more of a highlight rather than an innovation as most tanks are leak-resistant to some degree, well almost most tanks
Nice offer though @Vaporesso but not for me thanks, unless your looking to develop a GTi RBA coil for it
