Chocfox keycaps viability and stabilizers

[warningboatheli]

Hi Penk! I came across the ChocFox CFX BoW keycaps and was wondering if these would be viable in the Penkesu. They're 16.5 mm square whereas the MBKs are 17.5mm (horizontal) x 16.5mm (vertical). I don't want to ruin the aesthetic with big gaps, so I'm hoping the extra .5 mm wouldn't be atrocious?

Also, they weren't listed in your list of materials so I'm assuming you didn't use them, but I was wondering if you do or don't recommend adding stabilizers.

TIA! This is my first ever build, probably a little ambitious, but it's something I'm really excited to make!
