Templar heavy armored pvp support

Hi guys,

i'm not very experienced in ESO yet, and i'm leveling a Breton Templar atm. Is it possible to build this class in some sort of Paladin(ish) build?

Heavy Armor, 1h/sword + 2h with some heals and buffs for group pvp? i'm searching the interwebz for some paladin builds but they are all pretty old.

Something like the old wow paladin. A beacon of light in the battlefield, hard to kill and buffing/healing my teammates. I don't want to use a healing staff because it breaks with the paladin lore imho.

Would this be viable in PVP?
