MFB Shooter customization - Unintended Compatability?

Hey there, this is the first serious post I've made in here because this is the first chance I got to have something very interesting to contribute.

After weeks of having insufficent pay to get back into the game with the new equipment (being married makes it hard sometimes, no complaints though). I finally got my first Hybrid/Fusion system blade. I bought Dark Cancer (I don't see the need to call it Gasher even if thats the Hasbro name) and just for the lols I got out my old plastic system launch grip and tried to see if it fit. I didn't expect it to but it did, sure its a little loose but not so much so that it affects the launch. In fact I'm so used to launching with a grip since I bought this grip back when Beyblade was first brought stateside and I got the HMS grip as soon as I could, that I launched it better than I was without the grip.

I wouldn't recommend doing this if you can afford the new MFB grip of course. How would such a custom be viewed in the rules is what I am wondering. Also if you don't believe me and have the original grip, please give it a try, I assure you it won't damage your shooter, winder, or bey in any way. I would love to know the official views on this customization and I will go with whichever decision flys.

EDIT: If you wish to make any comment or ask me questions on this set up please do so.
This should probably be in the Random Beyblade Thoughts thread.
Should it? I thought here was appropriate since it is a launcher combo that probably hasn't been done by many other people in this forum. I will grant that this is a pretty random occurance, however, I feel it counts here a bit more since it is a question about parts customization even if it isn't a blade combi.
You're not expected to have seen this, but it has been discovered already:

Picture links have expired now, but there's the discussion for it, and also the rulings behind it.

In future, please use the Ask a Question thread, for such small questions. This forum is actually just for Beyblade Customisations, and even then, in its official sense, not aesthetic customisations.
