Converting a base checkpoint to an MVDream checkpoint

[KappaMund]

Is it possible to convert other checkpoints to MVDream checkpoint, for example basic SDXL checkpoint or custom SDXL 2.1?

No, we fine-tune the model to learn multi-view consistency, so you will need to do the same for other models such as SDXL. For other SD2.1 models (e.g. LORA), you may try to merge the models, not sure about consistency after that though...
