[Feature Request]: "Hybrid" Setting for attributes.

[Zanedor]

Is your feature request related to a problem? Please describe.
I'm planing to, at some point in the somewhat near future, use the fan made Classic World of Darkness Mixed Game Rules as the basis of a number of 20th anniversary games with some new players. The idea is a short-ish chronicle of V20 W20 and M20 each after each other to act as a kind of introduction to each of the main game lines while having a consistent set of base rules and Abilities sets across all the games thanks to the Mixed Game Rules. I was planing to use parts of the Mixed Game Rules 4.5e Update Patch, particularly the option to use 5th Edition attributes, in the games as everyone seems to like them, however I've run into an issue where the 5th edition option for attributes offered in Foundry automatically links Willpower to them which isn't exactly how we would like running Willpower. It's not a insurmountable issue but it is inconvenient and the solutions tend to lead to a bit of stat wonkyness on our end.

Describe the solution you'd like
The addition of a "Hybrid" option to the "Settings for attributes" selection in the "Rules Settings" window. "Hybrid" would act as a middle-ground between 20th and 5th edition, with Appearance and Perception exchanged for Composure and Resolve like in 5th but Willpower is still calculated as it's own stat as in 20th.
