Well since I'm frankly sick and tired of speccing pugs :P, I decided to come up with an idea that would be extremely simple to do and would make pugs with more than 10 people and less than 10 people viable options.
Since the default block health is 4000
afaik and 5 v 5's usually never end in stalemates now since teams can easily break through the blocks with ease. So since this works out so well, for each extra person added onto each team, the block health for the pug would be increased to 4800 to account for the extra person on each team. This would also mean if there were to be a 4 v 4, then the block health would be 3200 instead of 4000.
For those who can't do math, add 800 block health for each extra person over 5 people and for every player missing from a 5 v 5 take away 800 block health.
