Maus, a disposable stealthy platform is, in its very nature, wasteful, given the cost of stealth and the development costs associated with designing an LO UAS. I actually believe there is a niche for such a UAS but it isn't disposable and wouldn't be cheap. Moreover, LO combat platforms with external stores are still multiple orders of magnitude more stealthy than non-LO platforms with the same external stores so it isn't all doom and gloom when you carry more 'boom'. That's just plain physics.
