Err, not really 
Since both are written in PHP, we’d strongly prefer it if the two of you ended up maintaining a single project together. There’s much more to be gained from that.
I don’t know how specific @DanielMarquard’s code is to Crit Cola though; that might justify keeping the two codebases separate, at least in the short term.
On a different note, if you think you’d be able to make something like this for Discord, let me know, as that’s the type of work we’d be interested in sponsoring.
