Indeed. I'm thinking, however, to experiment with a hi-speed, variable 'chopper' on the blue-side... that-way, you could easily 'custom tune' the blue 'pulses' to what is going to be fairly 'predictable / consistent' pulse-trains from both the green and red...
(not sure what sort of 'delay' may-be introduced thru the red-process, if-any, vs the greens' pulse-timing.. dunno, no data on that at the moment... 
)
...and, like you say, it might not really 'matter', since, even-if you somehow got the three sources to 'blend' perfectly, timing-wise, it's all gonna change once you blow them thru retro-style blanking and scans... I've had some scans look very-nearly perfectly-cw, and some look quite 'dashy', depending on the 'interfernce' from the scan-rate, point-count, etc...
Sometimes, however, you can use this to your 'advantage' - one of the fx-modules we developed for our 'conversion-systems' a few-years back, was what we dubbed the 'sky-scan' - basically, a large-mirror 'cone-scanner' with a
variable-speed motor, that could be attached to the chassis / projector, and when you
scanned even simple-graphics onto it, and 'played' the scan-rate off the motor-speed rate off the pulse-train, you could create some
mind-blowing fx, that you could vary on the-fly - like, turn 5 simple dots, in a 'star formation', into 'dancing cheetoes'
... made for
incredible aerials that would-otherwise take
hours to program / animate, ... ie:
Attachment 23301Attachment 23298Attachment 23299Attachment 23300...and then, 'play' w/ scan-rate
vs the Q-Sw pulses..
Attachment 23297 
...especially-fun, was 'deconstructing' stills, ie, a simple test-pat,
(...recognize this? 
Attachment 23306 ...and watch it become a 'living' aerials super-star...
Nothing 'new', really - I file it under "Lessons Learned from Laserium / the 6B"
playing all these 'variables' off-each other can produce some simple to-achieve, yet jaw-dropping fx... chop, in-particular, is your very, very cool friend...
But again, personally, I envision this a mostly-strictly aerials / fx projector... but *really* bright, and - color!, vs just the ho-hum green... And Steve (photonbeam)'s suggestion of using the wave-plate attenuator is a great-idea for controlling red vs green % - even trying to 'color-balance' a bit... hah, now
that's funny...
cheers..

....and armed only with his trusty 21 Zorgawatt KTiOPO4...
Now, imagine that beaming into a foggy night, being fed with a KTP532.
