Bloodlines are interesting, flavourful, and fun, but don't seem to interact too much with the sorceror's casting schtick.
so I propose a pseudo spell-list to accompany them. Providing more ways to use new spell slots without adding spells. They could have variable "spell slot" costs for greater effects.
For example (and this list made me think I shouldn't have just gone alphabetically >.> )
Aberrant Bloodline
Spoiler:
LvL 1: Aberrant Reach: By expending 2 1rst level spell slots, you cause your aberrant blood to stir. You gain a 20ft enhancement to reach for 1round/caster level. This ability stacks with Long Limbs
LvL 2: Aberrant Resilliance: By expending 2 2nd level spell slots, you trigger the survival instincts of your ancestors. You gain 3 temporary hp/caster level for a duration of 1hour/caster level
LvL 3: Third Eye: By expending 2 3rd level spell slots, you grow a third eye in the center of your forehead. This eye has Darkvision 60 feet and a continuous detect magic effect. The eye can leave it's socket and scout ahead. It flies at a speed of 40ft per round (perfect maneuverability, use Sorceror's skill points). If the eye is ever more than 1 mile from the Sorceror, the spell dissapates.
LvL 4: Acidic Exhalation: By expending 2 4th level spell slots, a sorceror may let loose a 60ft cone of acidic vapours. DMG 1d12/caster Level (max 15). Ref Save half (DC = 10 + Cha Modifier + 6)
LvL 5: Heavy Stomp: By expending 3 5th level spell slots, a sorceror can cause an upheavel of earth and stone, creating Hampered Movement (Difficult Terrain + Obstacles) and creating a cloud of dust that acts as Obscuring Mist. This dust settles in 2 rounds. Range = Medium. Area = (2 10ft squares / level)
LvL 6: Aberrant Hide: By expending 4 6th level spell slots, a sorceror can harden his skin to dramatic extremes. He gains a bonus to Natural Armour = Caster Level, Damage Reduction (Caster Level/2) / - . Duration 1 round / level
LvL 7: Alien Physique. By expending 2 7th level spell slots, a sorceror can strengthen his otherwise frail physique. He gains a +8 unnamed bonus to Strength, a +6 unnamed bonus to Dexterity, and a +4 unnamed bonus to Constitution.
LvL 8: ????

Mind you these are
1) Completely Arbitrary
2) Probably wildly unbalanced
3) Just Examples
So I'm simply putting forth the idea
