IVA helmet switch: mod idea & help request

[Rjoande]

Hello everybody, pretty new to the forum even if I've followed it since I started play KSP, more than a year ago.

In the last weeks I was wondering if there are any mods outhere to let my kerbal take in and off their helmets in IVA. I know that probably Textures Replacer Replaced to this already, but it's not compatible with my modset. Other projects I've seen around may not work with the 1.12.x version of the game.

So I'm trying to figure out how to make a dedicated mod myself. There is a value in the .cfg files of the crewed parts that can be edited to allow Kerbals to wear helmet in IVA. My idea is to create a patch to allow changing this value in-flight. I can handle Module Manager quite well, but still on my first steps of understanding how to use B9 Part Switch.

This is the basic idea. I'd appreciate a feedback on that and any advice!

Future developments may also include auto switch for given situations (eg wearing helmet in suborbital situation), and/or allowing also suit switching in flight.
