I have been fiddling around with Nasir as a stealth deck. It seems ok. I think there are probably a number of optimisations to make to this list, but here it is for discussion anyhow.

I've found it works best in mid to late game, as it's heavily rig based. Once you're up and running, the corp will be weary to rez ice as it allows you to dump your hardware off the workshops, and if they do, they end up just providing more fuel for your breaker suite. Once set up, it seems as if unless servers are very deep, you always have the cash to get in.
I prefer Nasir for this build than the other shapers. Kate's economic bonus is actually a slight weakness here, you want to spend all your cash all the time. This is why first cut is almost certainly modded. I have found them to just sit in hand unless I have spent my money already then they become sortof useful. Exile can't work, Professor no, Chaos Theory is an option, but I prefer 45 cards (not sure what I would cut, though opus and modded look likely, and probably the second sol). The extra mem would be useful, but I want to to at least try a build that seems to naturally suit Nasir himself. Kit is a pretty good option for stealth lulz, but she would go about it a very different way. Due to influence Shaper seems the only option for a full stealth rig at the moment.
It is very strong once you have a couple of cloaks out, and recurring hardware support for the breakers. I haven't come across a server I couldn't break into once set up.
It has a very noteable weakness to trace and tag n bag. In my meta this isn't prevalent, but I could definitely see there being room for hard counters to that, probably some good ol carapaces.
I'm pretty sure there's something strong lurking in here, would be great to hear your feedback.
