Using insane.py from Martini 2

Is the insane.py script for Martini 2 suitable for use with Martini 3, as long as I just solvate the protein with simple water? I've noticed that the name of the water residue in Martini 3 is different from Martini 2 (WN vs W), are there any other differences that I should be aware of?

"Quick start with MARTINI 3

- Building your simulation box with a bilayer: As the mapping (and number of beads) of the main lipids did not change from version 2 to 3, you can continue using your favorite programs to build bilayers. We recommend Insane (12) or CHARMM-GUI (13, 14). Only remember to change the name of your water (from W to WN) and ions (from NA and CL to TNA and TCL, respectively) in your top file. PS: new cholesterol and glycolipid models for MARTINI 3 are not available yet.

I am interested in simulating a membrane with CHOL (and other lipids like cardiolipines) using martini v3 however the parameters of these lipids are not available yet.
Can I still use the old itp parameters for cholesterol and cardiolipin with Martini3, while at the same time using the new parameters for other lipids (like POPC and POG?)
Many thanks for the clarifications.
