on PGM2? that seems unlikely, PGM2 can't do any of the blending effects that the CV1K board does and since the DDP games make extensive (IMHO far too much) use of them it would have been something of a visual downgrade.
PGM2 is just a traditional arcade system in design with everything in ROM ready for instant access, while the CV1K is more like a computer where everything has to be loaded into RAM from ROM when it's needed. Converting from between architectures requires extensive reworking of the code and wouldn't make much financial sense.
