[help]SMD LED Compatible Zealios

[g3rain1]

I doubt they exist but would it be possible to make them? Zealios are Gaterons, and I'm pretty sure the housing is the same, at least the upper half looks like is. Now you can buy SMD LED compatible Gaterons here.
I'm wondering if these housing tops are the same as Zealios/standard Gaterons. And if so if it would be possible to acquire just the bottoms.

Broader question: I have a board with SMD LEDs and want to put Zealios on it. What can I do?
