What do you want to be? DPS?

Tanky. Is Tanky magicka viable?

Yes, but not at low levels. I think for a DK, stamina tanks are better.

You have to realise that some specific skills can be morphed so they used stamina and scale of stamina.
amnong them are unstable flame (morph from searing strike) and burning breath (morph from fiery breath). Those provide a good amount of dps for levelling (you only need to be full tank in dungeons, outside, even in group play you are better off dealing a good punch as well).
I would recommend using a sword and shield. That skillline also gives skills, and those all scale from stamina. From there I recommend puncture (morph in any way you like) and shield charge (good for interupts and as an opener, morph to shielded assault). The last slot I would recommend is a magica skill, but as it doesnt depend a lot on spell damage, and is for support you can still take it. It is green dragon blood for stamina and health regen.
That compliments your first bar. The second bar(once you unlock it) in dungeons can be used for tanking and outside I recommend using a 2h weapon there.

So use those magicka skills I named now to unlock the morphs and start using the sword and shield skills.

It's doable quite so. Most DK skills are magicka based anyhow, that gives you nice tanky bonuses.
Rule of thumb:

Ardent flame is your DPS skill line
Draconic abilities are support, cc, defense
Earther heart is your tanky toolbox.

Most Magicka DKs mix a destro staff in there for PvE. But you can also set up the ardent flame skills as your main dps source.

Keep in mind, if you wish to be a dedicated tank, shield defense / bash, breakfree, roll dodge are all stamina consuming things.

EDIT: Btw, DK skills are magicka based, but dont let that confuse you. Every build uses both magicka and stamina. Question is where your DPS coming from. If you are using weapons mostly, those need stam for damage.
