Cross blooded sorcerer ruling PLZ post your thougths

[Anbu002]

so im thinking of making a crossblodded sorcerer for my friends pathfinder game and i would like you guys's opinion on somthing
so im thinking of going elemental/draconic and my question is about the bloodline power of elemental it says

Bloodline Arcana: Whenever you cast a spell that deals energy damage, you can change the type of damage to match the type of your bloodline. This also changes the spell’s type to match the type of your bloodline.

so taking it as written it says to match my bloodline not my elemental bloodline so i should be abale to change it to match either my draconic or my elemental or just my elemental what do u guys think.

The elemental bloodline (http://www.d20pfsrd.com/classes/core-classes/sorcerer/bloodlines/bloodlines-from-paizo/elemental-bloodline/) was written before the Crossblooded (http://www.d20pfsrd.com/classes/core-classes/sorcerer/archetypes/paizo-sorcerer-archetypes/crossblooded/) sorcerer archetype came out with Ultimate Magic, so the language is based on the assumption that a sorcerer can have only one bloodline. Therefor the mention of "your bloodline" always refers to the elemental bloodline itself. If they wanted you to be able to choose, they would have written "one of your bloodlines".
The bloodline description also contains this text (emphasis mine), making it clear that it refers to the element you chose for the elemental bloodline:

At first level, you must select one of the four elements: air, earth, fire, or water. [...] A number of your abilities grant resistances and deal damage based on your element
