I have to agree with Jim. If it uses aiki, it's aikido. If it doesn't it isn't.
I agree that this is part of what makes a technique an Aikido technique, but the principles of Aiki are not only used by Aikidoka e.g. Aikijutsu where the end results maybe be completely different to a similiar looking Aikido technique.
For me it is more down to the protective spirit of Aikido. I believe that you can take almost any technique from another martial art and providing you apply it with a bit compassion for Uke & self control (In otherwords no permanent damage to the attacker) then you can call it an Aikido Technique regardless of what it looks like.
