Ok sorry, finally got to storage.
I think its doable from my estimations. I understand the pictures are hard to read depth but maybe gives you an idea.
The parking brake would definitely need to be modified a bit like they mention. But I think in the ''off'' position, the height between it and the clutch pedal are different enough for it to work. In other words, the parking brake should be far enough towards the driver it to not create too much issue.
Of course, this is a pretty crude mock up as you can see, so a more in depth analysis is definitely in order to make a better judgement.
The picture with my foot on the clutch is with it fully to the floor
