LyX ⇒ Switching between two document classes

[CSMR]

I'd like:
- to submit papers with a particular document class: article (econometrica)
- To have an ordinary document class for working in, posting to my webpage etc.

I'm happy with the standard "article" class, but it doesn't have some frontmatter environments that "article (econometrica)" has:
Keyword
Thanks Text
Authors Block
Address
RunAuthor

Also there are Custom/flex insets that "article (econometrica)" has that "article" does not have.

Questions:
-Is there a way to get keywords and thanks text using "article" or something that looks like "article".
-Is there a way to implement all these "article (econometrica)" fields while looking like "article".

Thanks!

I don't think so, not without manually editing the class, which requires detailed LaTeX knowledge.
I'd suggest trying out some of the other available classes and finding the right ones for your purposes.

Can conditional statements be inserted into a LaTeX document?

If class=A
then
