Don't see why not? You can technically do it. You can fly around like that all day.

But you may lose performance unless you can go up a tooth on the pinion and raise HS to make up for lost blade area.

And if you can't put another pinion on, you can always try raising the throws, going +/-14deg collective and +/-14 cyclic if your linkage/head/swash won't bind.

I fly 525 on my V2 and love it, but I run high HS.
