Only 0-3v (guessing it's 3.3v) on Blue PWM isn't good. The signal from controller is 0-5v. Something like a logic level converter or using a couple resistors to create a voltage divider would be required. Other than this I think your plan should work.
If you have some 4.7k and 9.1k resistors that will drop 5v to 3.3v. You can replace the 9.1k with a 10k as it's more popular, that would give about 3.4v out which would be safe.
Here's a voltage divider calculator showing how they connect, R1 is 4700 ohm and R2 is 9100 or 10000 ohm.

Just a guess but I think the current required on the Purple on/off 3v will be low just like the signals so you shouldn't have a problem connecting multiple to one pin. You can connect multiple light signals to a single channel.
If it turns out you need Brown +12 you could use a DC port for that but I agree it's probably not needed.
