Would I be stupid to swap systems?

Hi all, as the title says, would I be stupid to swap systems?

Background: I’m currently running 2 X-T2’s, 23 1.4, 56 1.2. 16-55 & 50-140. I mainly shoot travel/ landscape photos but I do occasionally do portraits/ weddings, that kind of stuff.

Recently, or actually a while now I’ve been longing for a FF Sony (A7III/ A7RIII) and I think I’ve convinced my self that’s the way to go. Here’s why:

- I want to get more into weddings & paid work. I feel the FF,  better low light, faster auto focus will benefit here.

- My Workflow; I am a Apple & Lightroom user and as we all know isn’t the best for post production on fuji raw files. Again Sony may be more beneficial here. I do also like to edit my files, I know the fuji colours are great, but I have my own style that I like so I won’t miss the colour profiles too much (except Arcos).

- there’s just something about the FF look which I can’t put my finger on which is drawing me in.

Yes, I have considered over and over upgrading to X-T3’s. I was waiting for the XPRO3 but the screen has put me off. Yes, I could also adapt my workflow, but I don’t really want to at this stage.

I also owned the X100s for years and got rid for the second X-T2. I miss that camera, so I’m keeping a close eye on the release of the X100V/ X200 to keep my finger in the fuji pie.

I guess I’m just looking for some reassurance or convincing otherwise at this stage.....
