Doubt they would consider a low hours DESO when they have guys with 1000s hours going for a cadet position.
If you apply for both its not a problem but you will be asked in the interview have you applied to anyone else and who would you rather end up working for? I am sure you are aware CX and KA are almost the same company so you can't really say much prefer KA in their interview and much prefer CX in the CX one as they may share notes. If I didn't have a license I would apply for both.
