no problem. Generally spoken the price for an exclusive character is usually 10x more than the price it is sold in the asset store or online markets. You can contact me on my email 2dgamearts@gmail.com if you have a character request.
Some of my character assets (Dark Thief, Light Assassin, Skeleton Army etc.) do match in art and style with the juggernaut character. Other than that I am afraid there are not many that goes 1:1 in art but would still work quite well together. Each artist draws in his own style making it difficult to "mix" different assets from different artists.
The closes to my art style would be probably this skilled artist
