[DIY] Two bloodline conversions for Bloodrager

[Melanis Zbri]

Hey folks. First post here, but fairly long-time reader. I've seen a couple of sorc conversions for bloodrager, but I cobbled two for an upcoming Iron Gods AP campaign. I did have a third, but it really fell apart (if someone has some suggestions for bloodline powers for a Stormsoul path, put a reply in here).

The two I did make up were rather easy, since both lines make the Sorc more combat/melee-focused. I'll only note the bits that differ from the original sorceror lines.

I'm looking for feedback from folks with a bit more Pathfinder-specific rules mastery. In both cases I didn't want to go too far afield from the original sorceror material, so I know they aren't terribly innovative. The goal wasn't to create new but to adapt existing for possible PC bloodrager use.

Boreal Bloodrager:

This one was realtively simple - a bloodline that turns the sorceror into a melee'ing frost giant-y sort of person.

Feats: Arcane Strike, Endurance, Power Attack, Skill Focus (Intimidate), Toughness ((needs 1-2 more))

Bonus spells: Enlarge Person (7th), Ice Slick (10th), Elemental Aura (Cold only) (13th), Wall of Ice (16th)
I switched out Rage for Ice Slick given the class has a built in barbarian rage. I wanted to swap out Wall of Ice as well but then thought it might be useful to have a more utility spell on the list.

Powers:
1st level - Cold Strike
4th level - Ice Walker
8th level - Snow Shroud
12th level - Terrain Mastery: Cold +4 (new, as the Ranger class ability, stacks with ranger/nature warden abilities of the same name)
16th level - Giant Form (when ranging, can assume Frost Giant form as the Giant Form I spell, each round transformed uses 2 round of rage; at level 20 it's a 1:1 ratio for duration)
20th level - Child of Ancient Winters

I've seen the Boreal version drafted up on this board, but I wanted to shy away from a Monkey Grip-type ability. So I kept that transformative element until the level 16 power - in part because bloodrager spell casting will never get the Giant Form spell but at that level it seemed appropriate to the combat ability the class otherwise has.

Nanite Bloodrager:

I was thinking of using this bloodline to make the class a bit more android-useful but had second thoughts and decided to stay with the idea.

Feats: Blind Fight, Combat Expertise, Dodge, Improved Disarm, Lightning Reflexes, Skill Focus (Knowledge: Engineering)

Bonus Spells: Body Capacitance (7th), Defensive Shock (10th), Miasmatic Form (13th), Echolocation (17th)
Changed up the level 1, moved the level 4 to 3, and brought in a 4th level that felt appropriate without going for offensive power.

Powers:
1: Nanite Strike (this is no longer counted as a poison but as a nanite infestation)
4: Nanite Surge
8: Nanotech Resurgence
12: Reactive Adaptation (at this level the bloodrager's nanites will reactively protect their body from any form of energy damage. The bloodrager gains the benefits of a Resist Energy spell cast as an immediate interrupt, at their full class level for a duration of 1/2 their bloodrager level. The energy type resisted must match the energy damage that triggers the interrupt. This ability can be used 3 times + Con modifier per day and lasts for 1 round per 2 bloodrager class levels)
16: Distributed Body
20: Living Swarm
