I would definitely go for size, Lorikeets can play very rough and you don't want the larger bird getting rough with a smaller bird, just a slightly uneven contest.
Scaley's have been paired up with Red Collars, Rainbows and Musk. This was done to get the different colours and mutations into those birds as the Scaley was the first one to develop mutations. So yes they can hybridize and yes the offspring are fertile and can re-produce.
Personally I would go for the Rainbow, they are roughly the same size (this does vary with individual birds the same as it does in humans) and after all the Red Collar is only a Sub-Species of the Rainbow. And I have not met a Rainbow that was not a total fool when it comes to playing.
