Modifying or replacing prebuilt enclosure

I bought a cheap Blackhawk Urban single hub board because I value portability above performance for my short flat commute, plus it is an easy unit to deck swap, which I already have done onto a 33" deck.

But I want to go further and stick it on a Boardup folding deck.

The enclosure is 24cm long x 10cm wide x 3cm thick which is too long for the back of the deck. What will fit though is an enclosure half the length x twice the width, or 12cm long x 20cm wide…same volume but almost square instead of rectangle.

Before tearing into the enclosure, just trying to gauge how feasible this sounds.

Got any pictures of it all?

I’ll try to link a photo
