Yes, but would you pay? If HTC posted a voting method where the highest voted for equipment was made. Every vote would cost, say $5.00. If you voted, and your choice won, the $5.00 would be deducted from your AH account, if you voted, and your choice lost, you get charged nothing.
Example:
new fighter choices
1. P-51H
2. P-38J
3. 109-K4
4. Ki-84
Every player would have the oppurtunity to vote on a new A/C model.
So let's say I voted for the P-51H and Wotan voted for the 109-K4. Then, 50 more people voted for the P-51H and only 30 voted for the 109-K4. The P-51H therefore recieved 51 votes

and the 109, only 31, therefore the P-51H wins.
Now, because I voted for the 51H, my AH account is charged the $5.00 and I am happy, and HTC gets $255.00 income to model the 51H. All the guys that voted for the 109-K4 might not be as happy, but they don't loose any money either.
Anyway, the next time HTC does a vote for a new plane, it could be choices between
1. P-38J
2. 109-K4
3. KI-84
4. (some new choice)
Eventually, the player's choices would all be modeled and HTC would be making extra $$$ in the process.
