Puppet not working with camera and continuous rasterize

Hi everyone, so this is a problem that's completely stopped my progress in an animation that I'm working on for my showreel.

Basically, there's a room with a character in it and I need the animation to start from a very strong close-up of the character's leg, which is animated using the Puppet tool and end on a quick zoom out which would reveal the whole character.

So naturally i zoom in with the camera and turn on continuous rasterize on the leg, so it doesn't loose quality. What I found odd and extremely troublesome is the fact that the puppet pins don't rescale accordingly to the camera zoom, so when it's zoomed in, the pins "disattach" from the leg, and stay in the same place on the screen, which obliterates the animation.

An additional problem is caused by the continuous rasterize option, which when turned on, seems to be disabling the animation overall, immobilizing the leg.

I'd like to ask you for any advice on that. In case there's no fix and it's just AE nature (on a side note I find it really strange that the puppet effect can't be used with a camera), I'd be really appreciative for any sort of idea on how to make this scene happen, using other tools maybe.

I tried Duik, (initially i didn't, cause the animations are really basic and Puppet is more that enough for what I need) but I couldn't attach the bones to the leg (the leg is just 1 layer, so I'm guessing that's the reason?)

Thank you for reading.
