Gents I think that these will work really well as grouphead lights. Size, water proofing and looks all seem spot on!
Wanted to share in case anyone is in the search like me!

They cost a fraction of mod kits and look identical.
Can anyone see a reason why they wouldnt work?
Also any tips on 220v to 12v transformer placement and wiring?

I've used these cheapo LED's from Aliexpress on a Linea in a café setting. They didn't last too long and had to replace the ones near the steam valve. The ad mentioned 'water proof' but obviously they weren't. The lens covering the LED would fall off and had tp be glued back. Saying that, they are so cheap I just replaced them as I went at 2€ a pop.

They should last much longer in a home setting. Go for it.
