I know that the typical way to do RGB backlighting with these switches is to drill a hole in the PCB under each key, and surface mount an RGB LED on the other side of the board, shining through the hole at the bottom of the switch.It depends on which type of switches you have. There are 2 kinds compatible with rgb leds. The ones with 4 small holes, where you put the led ON the switch and under the keycap, maybe tricky to find the right size of leds. The second one, have a long hole almost the size of the switch, that's for SMD leds as the ones you posted.
I dont know the model number of the LED's but it has been done, see here: https://imgur.com/a/Hmb6SRt
That is a proto pcb from the Revo team that produces the dr D keyboard and some other kits. It was a small run of pcbs and as far as i know, was never released. Led configuration is for the cherry RGB switches that have the space for it on the bottom casing.
Hope that album can help somehow
I have Cherry MX RGB switches. They have a teeny tiny hole, but way too small for a surface mount addressable LED.Show Image(https://dl.dropbox.com/s/jkqttyiedjolv1t/Photo%2012-07-2018%2C%2020%2055%2021.jpg?dl=0)

Actually the PCB that i linked above fits those. Its a really tiny rgb led

Wow, those are super tiny! Would they get better results than a larger one reverse mounted, I wonder?
There is a new RGB addressable led in a pretty small package, the APA102-2020
