Will it be possible to use RTP from multiple RPG Maker softwares at once? Say for exemple I want to use a song from VX Ace in MV, or sound effects? Personally not planning on using graphics from other RPG Maker version, but it's still something I am curious about

To continue on a theme similar to my other question: will it be possible to use RTP assets where they're not normally? For exemple moving an SE to an ME. Or using, for exemple, a character portrait as a picture, or as a tile? 

✅ Using VX Ace BGM to MV is okay. Same with SE. It's okay to place SE to BGS/ME.

❌ Just no trimming of audio file.

✅Resizing graphics such as images from VX Ace to MV Sprite sheet is okay, too. Color Hue Changer is okay for monsters.

❌ No editing: no recolors using external software. No creating new tileset that doesn't come with the engine. No Photoshop, no Gimp editing.
