I'm a bit pessimistic about versaility builds. Sword and a bursting smg are both close range weapons, so one should be enough to cover the same territory of offense right? Also, if you choose the dex influent smg, then why not go for knives instead of swords? Also you need to finish fights fast as you can't take too much hits standing toe-to-toe with the enemy with low con and wearing light armor (infused rathound leather probably) on a difficulty setting where dodge does not help you. Two different close range weapon might result in a too spaced out build instead of proper specialization, which might hurt on higher difficulties.
HOWEVER
Since I love to meddle with the wonderful character builder basically as much as playing the game itself, here's my take on the character:
(please enable trapper's belt + jackknife, order of feats doesn't necessarily have to be like this)
http://underrail.info.tm/build/?HgcQBwMDAwdQbgDCoCh-wqBJJQAlYGAtNGAAAAAAAABIMSbCo0ISEwAGSxU3Fkk-MCnCs9-_Juuust look at that eye-pleasing layout of only 3's, 7's and that sweet 18. DEX based build, so naturally excellent infiltration skills, lots of hits, fat crits & wet clits. High dex also means that we don't need to invest too much skill points to take advantage of professional employment of various explosives and traps, utilizing oppurtunist and vile weaponry with a single bear trap boosting damage significantly (and to detect enemy contraptions). Superb usage of grenades for both utility and precise, devastating AoE attacks thanks to the 3 proper feats. Knives mean tons of melee hits per round, so we'll be quite mobile thanks to fancy footwork and can take cover at the end of our turns and of course generally be stealthing everywhere. Yeah, so we'll bringing out the most of having a high dex value with appropriate weaponry, the feats to back them up and skills involved.
Since it's knives & smg's could've gone for 7 con and 3 strength not the other way around. It's a questions between having better bursts with Full-Auto with more carrying capacity, or instead of Full-Auto we can take the awesome Cut-Throat with significantly more hp.
Regards of crafting, you'll be able to bake hypercerebrix that will allow you to produce a good selection of consumables up to bullheads, grenades and mines up to mk IV + reach 105 mercantile with an additional underpie. Will also make items of max tier plasma and emp warfare with long lasting electroshock blades (due to power management) and that sweet high quality infused rathound leather armor to further boost those crits with both weapons. And despite planning to play on dominating difficulty, we still need decent evasion in order to not be torn to shreds from a single enemy grenade.
Oh yes, and no psi. F@ck that. This is a kickass post-apocaliptic 80's action hero build - don't care about any fancy magic!
