Why they didn't make a V-12 based on an existing V-8 for the Dodge Viper?

The biggest difference between Dodge and Ford V10s was the Triton was a fresh sheet of paper design and OHC; Dodge based theirs on the 318 OHV V8. Both make good torque, the Triton gets slightly better fuel economy. Roughly the same dimensions so yes, packaging issues VS torque needed for trucks obviated any reason to produce V12s

Fords V10 is based off the 5.4L V8.
