Loading other layouts while in a layout?

So I've come to a situation where it appears that the size of certain graphic objects is causing some pausing between layouts. For example:

Layout 1: normal image sizes, not very large, runs smooth

going to...

Layout 2: has larger image sizes and there is a pause/delay between the animated object in layout 2 showing visible, and the object beginning its animation sequence.

I haven't run this as an .exe, but I can see in debug that it's a matter of the new layout object taking too long to load.

Would the "Load/Unload" Textures action be useful for this? Like:

-Layout 2 has a bunch of objects/animations that need to be loaded, so...

-I make Layout 1 a loading screen, set it for a number of seconds, make it countdown, and when it's finished I make the game jump to Layout 2?
