Fuji Off camera flash w/Xpro1

[duns]

Im wanting to invest in off camera flash equipment for my Xpro1 and upcoming xpro2. Im looking at the Radiopopper jr2, possibly with Canon 600EX-RT speedlights in manual mode.
I kinda like going this route because of the absence extra receivers to trigger flash.

Will this configuration work with my Xpro1??
Also, what are other options?

Thanks

Cactus V6 with RF60? The transceiver is quite large though 3"x3". Anyone have this setup on their xpro1?

Damien Lovegrove is using the Cactus religiously, he definitely recommends it.
