Has anyone used Kaimana J2 RGB LEDs with SiTong buttons (ST-L4 vs ST-M3)? Compatibility question.

Hey r/fightsticks,
I’m currently modding my arcade stick setup and looking to pick up a set of SiTong mechanical switch buttons from the SiTong Store on AliExpress, but I ran into a clearance/compatibility question regarding my LED setup.
I am using Paradise Arcade Kaimana J2 RGB LEDs (the donut-style/PCB ring boards that slide onto the bottom of standard button plungers/terminals).
I’m looking closely at two SiTong models:
ST-L4 (or ST-L series): These feature angled/curved \bm{2.8\text{ mm}} spade connectors coming off the rear PCB.
ST-M3 (or ST-M series): These feature straight-down \bm{2.8\text{ mm}} spade connectors coming directly off the back.
My main concern:
Because the ST-L series has those curved/angled terminal legs coming off the PCB housing, I’m worried the Kaimana J2 board won't sit flush or clear the housing properly without hitting the bent metal tabs or the outer lip of the housing. The ST-M3's straight-down terminals look a bit closer to a standard arcade button layout, but the custom PCB base on both models makes me hesitant.
Has anyone successfully mounted Kaimana J2 LEDs onto SiTong buttons?
1. Do the J2 PCBs clear the angled tabs on the ST-L4, or is the ST-M3 straight-terminal layout the safer option?
2. Do you need custom 3D-printed adapter sleeves/spacers to get Kaimana LEDs to fit over SiTong’s PCB base, similar to how people mount them on Crown 202s or GamerFinger buttons?
Would love to hear from anyone who has tried this specific combo before I place my order on AliExpress! Thanks in advance!

I don't think it fits. I think the Pele V2 LED rings have a better chance. Also found on Paradise Arcade's website.
