Pull a PaleMoon? You mean, do something amazingly great?
I think it is pointless to try and get help from other Firefox forks - their ego would get in the way. Their ego is already getting in the way: "Pull a PaleMoon"? - give me a break! Waterfox and similar projects - what's the point? A little speed? You're always playing catch-up with the main code base and it's totally questionable whether the benefits outweigh the cost. Besides, if a Chrome interface is what you like, use Chrome for crying out loud. If fact, that's exactly what's happening - people who like a Chrome interface are abandoning Firefox to use Google Chrome and Firefox has lost over three quarters of its market share - it's not rocket science, people!
Unlike other Firefox "forks", PaleMoon has the virtue of preserving what was good about Firefox without losing anything in speed and functionality. The developers have been ultra-responsive in resolving issues with the browser - where they find the time to do all of this stuff and still have a life is beyond me. Personally, I have not run into any incompatibility issues with websites, except for the User Agent sniffers which can be handled with some alterations to About:Config and a stern complaint to the webmaster.
As far as getting additional programmers on the project are concerned, the PaleMoon project may pick up some disgruntled Mozilla programmers but I think that would have happened after Australis, so don't count on it. Additional help will come from programmers who discover PaleMoon and want to support it - that again is why advertizing is so very important. The stability and reliability of the Goanna parser will be another attractive feature - as a programmer, I get tired of having to deal with "the next great thing" every 3 months, which usually turns out to be either a renaming of old technology or a lot of flash and bang with little substance. Give me something I can sink my teeth into!
As I said in an earlier post, I believe in what the PaleMoon project is trying to do and I will help out at the first opportunity. In the meantime, I think this garbage that people are pushing, trying to turn PaleMoon into some sort of negative proverb, is a disservice to the project and to the people who have put many hours into making PaleMoon a success.
