Is it possible to combine elements of different Demo Themes in WordPress?

Hi,

I have been working on a website for a long time now, we are close to finalising it, however what is holding us up are various problems with the Enfold Theme, so we decided to instead, use a combination of Enfold demo theme elements for our website which we then would like to fill with content. My question is:

1. In wordpress, what is the best way to merge various demo theme components together and how do i import Demo Theme content without breaking the original page?

I have a second workspace available i could use to build a page to then load onto the current domain, i however do not know how to migrate the page safely.

2. Our current website is set to use a boxed layout because the animated numbers dont work with the full width layout, unless the viewport is directly aimed at the animated numbers and the browser window is then resized. is it possible to fix this somehow? All plugins have been disabled and it appears to work with other pages that are not the main page, i have no clue what could be causing it but its likely a JS issue…

help would be highly apprechiated,
Regards,
Kai / Phoenix
