If you want a sexy name I am sure there are better answers listed above. But it has been my experience in retail industry that when a company offers multiple similar related items, it needs to be kept as simple as possible. An example being I had to re-read your first posts a few times to be sure what exactly you were building. I could see by your complete explanation you were concerned we might get confused. You can also see this in the posts above, not everyone understood how many you ask for.
Fred Bear did this right with his takedown bows, risers were named A, B C, limbs were 1,2,3. That is very easy to understand. 40 years later, we still understand his versions of this bow.
In doing this customers will better understand what you have to offer. How many people do you thng will not be able to spell or even pronounce some of the names suggested above? You are in the business to sell bows, not make fancy names. If you make a great product, the name will not matter too much. A customer understanding the product and knowing what to order is far more important.
So, I suggest you consider this;
Name your Riser A and B, name your patterns 1,2, and 3. Like this; AR-1, AR-2, AR-3 (AR representing model A Riser, pattern 1, 2 and 3) and BR-1, BR-2, and BR-3. You could also add an L or R for left or right hand, such as BR-2R.
If you expand models in the future it will be easy to add a new number that your customers will understand.
Good luck with your venture.
