Advice - 3D Printing Bespoke Action Figures For Stop Motion Animation

I am working on a small stop motion production that features 5 x bespoke action figures. We filmed a test using the T13 action figures with moveable joints and these worked really well in terms of their size/functionality. We need to customise them to create 5 different evil characters. It looks like this is potentially possible by getting a custom STL file design 3D printed and added to the base of the standard T13 action figure.

Does anyone know if this is doable? And if so, have any advice re how I can go about finding someone / or an organisation that could help us do this? We need to get an idea of the budget/time required to produce 5 x custom evil figures. 

We can be relatively flexible with what they look like but they do need to look evil and avoid any copyright issues - so they can't be too similar to any trademarked characters. Our creative team have brainstormed some of the types characters they have in mind - I've attached the visual here. Obviously some of these reference existing characters which we can't do, and we appreciate 3D printing won't necessarily come with the smooth finishes shown here. We thought 3D printing was worth exploring.

Any advice/thoughts welcome as we're all new to 3D printing.

Thank you in advance for any info you can share
