dont you have to honor and kill stuff to get that? how is a miner lumberjack smith tailer char to do that?
What are you doing that you need to stealth by?
In pvp situations you would either recall/SJ, run away or die. In pvm, use a confusion blast potion, or invis potion, or invis spell, simply run away. Third option would be to mine/chop within guardzones.
Basically if you put nothing toward defenses then stroll into danger you dig your own grave. I would assume you have some skill points to throw into camping - unless you were planning to use JoaT - so why not put some into magery? Alternatively you can get at least 55 magery from items (book, jewels, talisman) and use invis scrolls.
I think allowing use of soul stones out in the field would be a bad move for any number of reasons.
