There are a lot of other Oracle curses out there to avoid cheese. Lame is probably my least favourite of the usual ones, I must admit. By taking the Primalist Archetype you can pick up Moment of Clarity to heal yourself pretty quickly - something a Bloodrager/Barbarian can occasionally need, despite your damage sponge nature - and as a bonus, if you're a Life Oracle and have Life Link running, you can soak up a fair bit of damage for your squishy team mates too.
Have you considered Skald instead of Bard? It's abilities gel well with a raging class, and can effectively give you even more rage.
If an ally has her own rage class ability (such as barbarian's rage, bloodrager's bloodrage, or skald's inspired rage), she may use the Strength, Constitution, and Will saving throw bonuses, as well as AC penalties, based on her own ability and level instead of those from the skald (still suffering no fatigue afterward).
You are, of course, your own ally, meaning your own Bloodrage will work for it. Without Fatigue. And getting the rest of your Martial buddies up and at 'em.
And as a bonus...
If the skald has rage powers from another source, he (but not his allies) can use those rage powers during an inspired rage. He cannot select a duplicate rage power, unless that rage power can be taken multiple times.
If the skald has the ability to rage from another source, he can use his skald rage powers during that rage as well.
It'll multiple your rage abilities, and grant you a significant ability to buff your martial allies, and that's a nice trick.
A spirit dancer medium could be an interesting and appropriate gestalt for you. Psychic spells can be cast in armor just fine and you can pull up the right ability for almost any situation. Including the champion spirit to just hit things harder.
Ranger or slayer to nab natural weapon feats from fighting style? Brawlwe for martial flexibility?
If you go sorcerer, I recomend thie eldritch scrapper.
Paladin for more layers of defense?
