Your options are:
Dual mod. Would require a TE2 crossbone + a ps4 pcb (such as the Brook board you linked to or a padhack) since the Xbone TE2 is not common ground.
Install one of the new Brook 4 in one boards. Basically you would be disconnecting the circuitry in your stick and using this as the brains/output. It works with ps4, ps3, xbone, and 360 (pc also, of course).
Use a converter. There’s the brook xbone to ps4 converter and the newest CronusMax+. The brook is reportedly a much better option, as the Cronus requires a ps4 controller for authentication and usb hub workaround to bypass the 8 minute timeout (which isn’t a factor with the Brook products).
One note on the Brook products: you’ll have to keep up with firmware updates, as Sony has locked them out at least a couple times already now. Brook has had fixes out extremely fast so far. This is the only edge a padhack or the cronus has on brook’s ps4 products.
I believe LED’s would only work in xbone mode with a dual mod. The brook 4 in one would require an aftermarket LED controller, and I don’t know if they will work with a converter. I would assume so, but can’t say for sure about any of the LED stuff really, as I haven’t messed with them.
