Thanks Echolot, I appreciate your response. I have decided to make my mod installable with JSGME by loading a pre-defined profile. I will include instructions that this can only be done with 1.2.0 game and Generic Patcher applied.
Making an installer has shown to be too complex for me
Thanks for your feedback, this may be useful for other modders at some point I think!
Cheers,

XS
