Complex chain you've got going on there!
I like chorus last, distortion will make the effect less pronounced, but then again you might want that!
The Bass Big Muff works really well with a dirty overdrive on front. I do this and set the BBM to dry mode so I in effect have overdrive mixed with boosted fuzz. Some fuzzes don't respond well with an overdrive in front, and same goes for some overdrives, so it really depends on the pedals in question.
About those ODs - I didn't like the Joyo UD on bass, but I think it would work well in your application where low end loss is not an issue. It does sound harsh compared to some other pedals though, so depends if that's what you want. I have a Speaker Cranker and love it - although it's not very flexible with it's single gain knob. I use it as a dirty boost near the end of my chain. I use an SFT in front of my BBM, both that and the BB Preamp work really well in front of it in my experience - but you're already sending it a dirty high-passed signal, so it's hard to judge what would work best in your setup!
