Using two handed over bow is a dps loss, but it's doable. Stam dk played correctly can pull the highest dps in the game. It's all about stacking dots and being consistent in rotation. And using 2h doesn't give us anything we need and without bow we lose a couple important skills. Basically with the maelstrom daggers rapid strikes buffs the next dot used after it which works well with the dks class abilities. Skills like venomous claw, noxious breath, trap beast, caltrops, poison arrow, endless hail, rending slashes are what everyone is using. Use steel tornado for aoe. For gear night mothers gaze, hundings rage, or tbs are all good. Valkyn skoria, mephalas, or Kena are good options. Maelstrom weapons are really useful here but without them you'll still do high damage

If you care to watch a 14 minute video I just recently uploaded a guide for my Stam DK build on youtube:
It's a dot build which is able to achieve incredibly high single target DPS and is specifically designed for trials, although it works for all PvE content.

This setup revolves around Dual Wield and Bow. Anyway take a look and see if it's something for you.
