Unfortunately, No. You application stated that you wanted VIP on one account and is associated with one channel, thus you are expected to maintain that association in order to keep your rank. If you don't maintain that association, then you don't keep your rank.
If you choose to switch channels and still record MCG on the new channel, then your VIP account would stay, but note that you would essentially be putting a lifespan on your VIP. Currently, VIP rank for Youtubers are granted to a single person for a single channel for simplicity's sake, as it makes tracking easier for both us and your audience. However, if you change your channel, your old channel that earned you the VIP rank will basically be seen as non-active since that's the account you are associated with through your VIP application. So once we do our next VIP check, and we see that your channel hasn't been uploading videos in a while (because you've moved channels), you will be marked inactive and likely have your VIP removed.
If you choose to switch channels and stop recording MCG, it's basically the same thing but accelerated. Your account really would be inactive, and your new account wouldn't qualify for VIP, so you'd lose your rank.
The best way to actually do this and keep VIP would be if your new channel passes for VIP, so you just fill out a new app and get it accepted, then let the other app for your old channel expire naturally.
I don't really know why a Youtuber would want to change channels, thus abandon their previous work and fame. This is not a situation we expected to happen, but that is how our policy must be interpreted.
